Possible causes include age-related fertility changes, ovulation problems, changes in sperm quality, blocked fallopian tubes, endometriosis, uterine conditions, hormonal disorders, lifestyle factors, or a combination of factors. GFC provides comprehensive <a href=\"https:\/\/genesisfertility.co.th\/en\/service\/\">fertility services in Thailand<\/a>, including IVF, ICSI, <a href=\"https:\/\/genesisfertility.co.th\/en\/services\/iui\/\">IUI<\/a>, egg freezing, PGT-A genetic testing, and fertility counseling for international patients.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The important point is that previous fertility does not guarantee current fertility. Fertility can change between pregnancies, and many causes of secondary infertility can be evaluated and treated.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Secondary Infertility?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Secondary infertility is difficulty achieving a pregnancy after a previous pregnancy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is different from primary infertility, which refers to difficulty achieving a first pregnancy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A previous successful pregnancy does not mean that fertility remains unchanged. Age, medical conditions, surgery, infections, medications, reproductive health and changes in sperm quality can all affect fertility over time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Secondary infertility can involve the female partner, male partner, both partners, or remain unexplained after standard testing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Primary vs. Secondary Infertility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Type<\/th><th>Meaning<\/th><\/tr><\/thead><tbody><tr><td>Primary infertility<\/td><td>Difficulty achieving a first pregnancy<\/td><\/tr><tr><td>Secondary infertility<\/td><td>Difficulty achieving a pregnancy after a previous pregnancy<\/td><\/tr><tr><td>Male-factor infertility<\/td><td>Fertility problems related primarily to sperm or the male reproductive system<\/td><\/tr><tr><td>Female-factor infertility<\/td><td>Fertility problems involving ovulation, eggs, fallopian tubes, uterus or reproductive hormones<\/td><\/tr><tr><td>Combined-factor infertility<\/td><td>Fertility factors are identified in both partners<\/td><\/tr><tr><td>Unexplained infertility<\/td><td>Standard evaluation does not identify a clear cause<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Infertility is not always caused by one partner.

The WHO report on infertility provides global estimates showing that approximately 17.5% of the adult population experience infertility, highlighting the need for increased access to affordable fertility treatment. [<em>source: <a href=\"https:\/\/academic.oup.com\/humrep\/article\/41\/1\/25\/8345643\" target=\"_blank\" rel=\"noopener\">academic.oup.com<\/a><\/em>]<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Having conceived previously does not remove the possibility of infertility later. Secondary infertility can become an important concern when a couple is trying to conceive again.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Causes Secondary Infertility in Women?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Several female reproductive factors can make a second pregnancy more difficult.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Does Age Affect Secondary Infertility?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Female age is one of the most important factors in fertility planning because both egg quantity and egg quality naturally decline over time. The <a href=\"https:\/\/www.acog.org\/womens-health\/faqs\/having-a-baby-after-age-35-how-aging-affects-fertility-and-pregnancy\" target=\"_blank\" rel=\"noopener\">ACOG explains how age affects fertility<\/a>, including the relationship between age, fertility decline, and <a href=\"https:\/\/genesisfertility.co.th\/en\/services\/egg-freezing-thailand\/\">egg freezing<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As women age, the number and quality of available eggs generally decline. This can make conception more difficult and can also affect the chance of a successful pregnancy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This becomes particularly important when several years have passed since the previous pregnancy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Someone who conceived easily at a younger age may have a different fertility profile when trying to conceive later.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For women aged 35 and older, fertility evaluation is generally recommended sooner because age is an important predictor of reproductive potential.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Can Ovulation Problems Cause Secondary Infertility?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Ovulation is necessary for an egg to be released and available for fertilization.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ovulation can become irregular or stop because of conditions such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>PCOS<\/li>\n\n\n\n<li>Thyroid disorders<\/li>\n\n\n\n<li>Significant weight changes<\/li>\n\n\n\n<li>Hormonal disorders<\/li>\n\n\n\n<li>Elevated prolactin<\/li>\n\n\n\n<li>Certain medications<\/li>\n\n\n\n<li>Other endocrine conditions<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Irregular or absent periods can be an important clue that ovulation may not be occurring regularly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Can Endometriosis Cause Secondary Infertility?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Endometriosis occurs when tissue similar to the lining of the uterus grows outside the uterus.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It can affect fertility through inflammation, pelvic adhesions, changes in pelvic anatomy and problems involving the ovaries or fallopian tubes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A woman may not have experienced significant symptoms during her first pregnancy but can develop or experience progression of endometriosis later.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Can Blocked Fallopian Tubes Cause Secondary Infertility?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. The fallopian tubes provide the pathway where sperm and egg normally meet.<br>Tubal blockage or damage can result from:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pelvic inflammatory disease<\/li>\n\n\n\n<li>Previous pelvic or abdominal surgery<\/li>\n\n\n\n<li>Certain infections<\/li>\n\n\n\n<li>Endometriosis<\/li>\n\n\n\n<li>Pelvic adhesions<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A previous pregnancy does not rule out a later tubal problem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If there is a history of pelvic infection, surgery or endometriosis, your fertility specialist may recommend testing the fallopian tubes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Can Fibroids or Other Uterine Problems Affect Fertility?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, depending on the condition.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Uterine conditions that may affect conception or implantation include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fibroids<\/li>\n\n\n\n<li>Endometrial polyps<\/li>\n\n\n\n<li>Adenomyosis<\/li>\n\n\n\n<li>Congenital uterine abnormalities<\/li>\n\n\n\n<li>Intrauterine adhesions<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">However, not every uterine abnormality requires treatment.<br>Its location, size, severity and effect on the uterine cavity all matter. Your doctor should determine whether a finding is clinically relevant before recommending treatment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Can Pregnancy or Surgery Affect Fertility Later?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Pregnancy and childbirth can be followed by medical or surgical events that may be relevant when evaluating secondary infertility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your doctor may consider a history of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Cesarean delivery<\/li>\n\n\n\n<li>Pelvic surgery<\/li>\n\n\n\n<li>Uterine surgery<\/li>\n\n\n\n<li>Pelvic infection<\/li>\n\n\n\n<li>Postpartum complications<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A previous Cesarean section does not automatically cause secondary infertility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The important question is whether there is evidence of adhesions, tubal problems, uterine abnormalities or another condition that could affect fertility.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Can Breastfeeding Make It Harder to Get Pregnant?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, temporarily in some women.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Breastfeeding can suppress ovulation because of hormonal changes associated with lactation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, breastfeeding does not always prevent pregnancy. Ovulation can return before regular menstrual periods resume, and the effect varies between individuals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are breastfeeding while trying to conceive, discuss your menstrual cycle and reproductive plans with your healthcare professional.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<style>\n  .gfc-line-wrap { text-align: center; margin: 24px 0; }<br \/>\n  .gfc-line-btn {<br \/>\n    display: inline-flex;<br \/>\n    align-items: center;<br \/>\n    gap: 12px;<br \/>\n    background-color: #06C755;<br \/>\n    color: #ffffff !important;<br \/>\n    font-family: inherit;<br \/>\n    font-size: 18px;<br \/>\n    font-weight: 700;<br \/>\n    line-height: 1;<br \/>\n    letter-spacing: 0.2px;<br \/>\n    text-decoration: none !important;<br \/>\n    padding: 15px 34px;<br \/>\n    border-radius: 9999px;<br \/>\n    box-shadow: 0 6px 18px rgba(6, 199, 85, 0.30);<br \/>\n    transition: background-color .2s ease, transform .2s ease, box-shadow .2s ease;<br \/>\n  }<br \/>\n  .gfc-line-btn:hover,<br \/>\n  .gfc-line-btn:focus {<br \/>\n    background-color: #05B34C;<br \/>\n    transform: translateY(-2px);<br \/>\n    box-shadow: 0 10px 24px rgba(6, 199, 85, 0.40);<br \/>\n    color: #ffffff !important;<br \/>\n  }<br \/>\n  .gfc-line-btn:active { transform: translateY(0); }<br \/>\n  .gfc-line-btn svg { width: 26px; height: 26px; flex: none; }<br \/>\n  @media (max-width: 480px) {<br \/>\n    .gfc-line-btn { display: inline-flex; width: 100%; justify-content: center; padding: 15px 24px; font-size: 17px; }<br \/>\n  }<br \/>\n<\/style>\n\n\n\n<style>\n  .gfc-line-wrap { text-align: center; margin: 24px 0; }\n  .gfc-line-btn {\n    display: inline-flex;\n    align-items: center;\n    gap: 12px;\n    background-color: #06C755;\n    color: #ffffff !important;\n    font-family: inherit;\n    font-size: 18px;\n    font-weight: 700;\n    line-height: 1;\n    letter-spacing: 0.2px;\n    text-decoration: none !important;\n    padding: 15px 34px;\n    border-radius: 9999px;\n    box-shadow: 0 6px 18px rgba(6, 199, 85, 0.30);\n    transition: background-color .2s ease, transform .2s ease, box-shadow .2s ease;\n  }\n  .gfc-line-btn:hover,\n  .gfc-line-btn:focus {\n    background-color: #05B34C;\n    transform: translateY(-2px);\n    box-shadow: 0 10px 24px rgba(6, 199, 85, 0.40);\n    color: #ffffff !important;\n  }\n  .gfc-line-btn:active { transform: translateY(0); }\n  .gfc-line-btn svg { width: 26px; height: 26px; flex: none; }\n  @media (max-width: 480px) {\n    .gfc-line-btn { display: inline-flex; width: 100%; justify-content: center; padding: 15px 24px; font-size: 17px; }\n  }\n<\/style>\n\n<div class=\"gfc-line-wrap\">\n  <a class=\"gfc-line-btn\" href=\"https:\/\/page.line.me\/gfcclinic?openQrModal=true\" target=\"_blank\" rel=\"noopener\">\n    <svg viewBox=\"0 0 24 24\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" aria-hidden=\"true\">\n      <path fill=\"#ffffff\" d=\"M12 3C6.477 3 2 6.66 2 11.17c0 4.04 3.55 7.42 8.35 8.06.325.07.767.214.879.492.1.252.066.646.032.9l-.142.854c-.043.252-.2.986.864.538 1.064-.448 5.74-3.38 7.83-5.788C21.286 14.6 22 12.98 22 11.17 22 6.66 17.523 3 12 3zM8.11 13.42H6.13a.523.523 0 0 1-.523-.522v-3.96a.523.523 0 0 1 1.046 0v3.437H8.11a.523.523 0 0 1 0 1.045zm2.05-.522a.523.523 0 0 1-1.046 0v-3.96a.523.523 0 0 1 1.046 0v3.96zm4.77 0a.523.523 0 0 1-.358.496.53.53 0 0 1-.165.026.52.52 0 0 1-.42-.21l-2.03-2.762v2.45a.523.523 0 0 1-1.046 0v-3.96a.522.522 0 0 1 .94-.313l2.033 2.766V8.938a.523.523 0 0 1 1.046 0v3.96zm3.2-2.503a.523.523 0 0 1 0 1.046h-1.457v.934h1.457a.523.523 0 0 1 0 1.045H16.32a.523.523 0 0 1-.522-.522v-3.96a.523.523 0 0 1 .522-.523h1.98a.523.523 0 0 1 0 1.046h-1.457v.934h1.457z\"\/>\n    <\/svg>\n    Chat with us on LINE\n  <\/a>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Can Men Have Secondary Infertility?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes.

Tests such as HSG may be used to assess the fallopian tubes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For men, evaluation commonly includes medical and reproductive history and semen analysis, with hormonal or additional testing when indicated.<\/p>\n\n\n\n<figure class=\"wp-block-image is-resized\"><img decoding=\"async\" src=\"https:\/\/genesisfertility.co.th\/wp-content\/uploads\/2025\/10\/How-Is-Secondary-Infertility-Diagnosed.png\" alt=\"fertility testing\" style=\"aspect-ratio:1.3157894736842106;width:600px;height:auto\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Does AMH Tell You If You Can Get Pregnant?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">No. AMH is mainly used to assess ovarian reserve and help predict ovarian response during fertility treatment. It does not by itself determine whether you can conceive naturally. Results should be interpreted alongside age, menstrual history, ultrasound findings and other fertility factors. Learn more about <a href=\"https:\/\/genesisfertility.co.th\/en\/amh-test-ovarian-reserve\/\">AMH testing and ovarian reserve<\/a>, including how AMH levels are interpreted alongside age, ultrasound findings, and other fertility factors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Is Secondary Infertility Treated?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There is no single treatment for secondary infertility. The right approach depends on the cause, age, ovarian reserve, sperm quality, fallopian tubes, uterus and previous fertility history.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Treatment may include addressing lifestyle or medical factors, treating ovulation problems, managing selected tubal or uterine conditions, or using IUI, IVF or ICSI when appropriate. For couples considering assisted reproductive technology, learn more about <a href=\"https:\/\/genesisfertility.co.th\/en\/services\/ivf-icsi-bangkok\/\">ICSI treatment<\/a>, including indications, success rates, and package options.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can Fertility Problems Be Treated First?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, when appropriate. Your doctor may address factors such as smoking, excessive alcohol use, significant weight changes, hormonal disorders, certain medications or poorly controlled medical conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If ovulation is irregular or absent, treatment may involve medication or management of the underlying hormonal or metabolic condition. Tubal or uterine problems may require medical or surgical treatment, while some conditions may be managed with fertility treatment instead.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is IUI an Option for Secondary Infertility?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It can be. IUI may be considered when ovulation, fallopian tubes and sperm parameters are suitable. The decision also depends on age, duration of infertility and previous treatment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">When Is IVF or ICSI Considered?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">IVF or ICSI may be appropriate when there are specific clinical indications, such as significant tubal disease, certain male-factor fertility problems, reduced reproductive potential or previous unsuccessful treatment. Review GFC&#8217;s current <a href=\"https:\/\/genesisfertility.co.th\/en\/icsi-price-packages-2026\/\">ICSI costs<\/a> for package tiers, eligibility criteria, medication limits, and additional services.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Having conceived naturally before does not mean you need ICSI for a subsequent pregnancy. Your fertility specialist should evaluate both partners and recommend the treatment that best fits your current fertility situation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can Secondary Infertility Be Treated?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In many cases, yes. Some causes can be treated medically or surgically. Other couples may require assisted reproductive technology.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Treatment outcomes depend on factors such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Female age<\/li>\n\n\n\n<li>Ovarian reserve<\/li>\n\n\n\n<li>Sperm quality<\/li>\n\n\n\n<li>Cause and duration of infertility<\/li>\n\n\n\n<li>Tubal and uterine health<\/li>\n\n\n\n<li>Previous pregnancies and treatments<\/li>\n\n\n\n<li>Overall reproductive health<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">There is no single treatment that works for every couple.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An individualized fertility evaluation is more useful than assuming that the same treatment that worked for the first pregnancy will work again.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Can You Do While Trying to Conceive Again?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you are planning another pregnancy:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Consider your age-related fertility timeline.<\/li>\n\n\n\n<li>Track menstrual cycles and ovulation when appropriate.<\/li>\n\n\n\n<li>Review medications and supplements with a healthcare professional.<\/li>\n\n\n\n<li>Avoid smoking and recreational drugs.<\/li>\n\n\n\n<li>Limit alcohol while trying to conceive.<\/li>\n\n\n\n<li>Maintain a healthy lifestyle and manage chronic conditions.<\/li>\n\n\n\n<li>Seek medical advice if periods are irregular or absent.<\/li>\n\n\n\n<li>Do not assume that previous fertility means current fertility is unchanged.<\/li>\n\n\n\n<li>Consider evaluation of both partners when indicated.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">The goal is not to place responsibility on one partner. Both partners contribute to reproductive outcomes and may need evaluation.

It can result from female factors, male factors, combined factors or unexplained infertility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why is it harder to have a second baby?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fertility can change between pregnancies. Age-related fertility decline, changes in sperm quality, ovulation problems, tubal or uterine conditions, endometriosis, medical conditions, medications and lifestyle factors can all contribute.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Can men experience secondary infertility?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. A man may have fathered a child previously but later develop changes in sperm production or quality, hormonal problems, reproductive conditions or other factors affecting fertility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Does age affect secondary infertility?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. Female age is an important factor in fertility. This is why fertility evaluation is generally recommended after six months of trying for women aged 35 or older, or sooner when there are other risk factors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Can breastfeeding make it harder to get pregnant?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Breastfeeding can temporarily suppress ovulation in some women. However, pregnancy can occur before regular menstrual cycles return.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Do I need fertility testing if I already have a child?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you meet the criteria for an infertility evaluation, previous pregnancy does not eliminate the need for testing. Both partners may need to be evaluated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When should I see a fertility specialist?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Generally, evaluation is recommended after 12 months of trying if the woman is under 35 and after six months if she is 35 or older. Earlier evaluation may be appropriate when there are irregular periods, suspected tubal or uterine disease, endometriosis, suspected male-factor infertility or other relevant medical factors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Is IVF always necessary for secondary infertility?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No. Treatment depends on the cause. Some couples may conceive after treatment of an underlying condition, while others may benefit from IUI, IVF or ICSI.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Is ICSI better than IUI for secondary infertility?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Neither treatment is automatically better for everyone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">IUI and IVF\/ICSI are used for different clinical situations. The appropriate option depends on factors such as age, ovarian and tubal status, sperm quality, duration of infertility, previous treatment and the couple&#8217;s goals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Can secondary infertility be cured?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some causes can be treated or corrected, while others may require fertility treatment to achieve pregnancy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The first step is identifying the factors affecting fertility and developing a treatment plan based on the couple&#8217;s individual situation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<style>\n  .gfc-cta-row {<br \/>\n    display: flex;<br \/>\n    flex-wrap: wrap;<br \/>\n    gap: 14px;<br \/>\n    justify-content: center;<br \/>\n    align-items: center;<br \/>\n    margin: 24px 0;<br \/>\n  }<br \/>\n  .gfc-cta-row a {<br \/>\n    display: inline-flex;<br \/>\n    align-items: center;<br \/>\n    justify-content: center;<br \/>\n    gap: 12px;<br \/>\n    color: #ffffff !important;<br \/>\n    font-family: inherit;<br \/>\n    font-size: 18px;<br \/>\n    font-weight: 700;<br \/>\n    line-height: 1;<br \/>\n    letter-spacing: 0.2px;<br \/>\n    text-decoration: none !important;<br \/>\n    padding: 17px 34px;<br \/>\n    border-radius: 9999px;<br \/>\n    transition: background-color .2s ease, transform .2s ease, box-shadow .2s ease;<br \/>\n  }<br \/>\n  .gfc-cta-row a:active { transform: translateY(0);
