The only difference is how the egg is fertilised: naturally (IVF) or by direct injection (ICSI). ICSI is recommended mainly for male-factor infertility, previous fertilisation failure, or when embryos will be genetically tested.

In\u00a0<em>conventional<\/em> IVF, thousands of sperm are placed around each egg and one fertilises it on its own, the natural route, outside the body. Conventional IVF works well when sperm quality is good. The UK&#8217;s <a href=\"https:\/\/www.nhs.uk\/conditions\/ivf\/\" target=\"_blank\" rel=\"noopener\">NHS<\/a>\u00a0describes IVF as one of several techniques to help a couple conceive, used after simpler options.<\/p><ul><li>After collecting both eggs and sperm, the physician places them together in a laboratory culture dish, allowing the sperm to naturally penetrate the egg&#8217;s outer shell and fertilize it on its own.\u00a0<\/li><li>This differs from ICSI, where a sperm is directly injected. Once fertilization occurs, the embryos are cultured in a specialized incubator for 3 to 5 days until they reach the appropriate stage for transfer.<\/li><\/ul><h2>What Is ICSI?<\/h2><p>ICSI (intracytoplasmic sperm injection) is a specialised form of IVF. An embryologist selects the single strongest sperm and injects it directly into the egg with a fine glass needle. Every other step \u2014 stimulation, egg collection, embryo culture, transfer \u2014 is identical to IVF. ICSI was developed specifically for male-factor infertility, and the\u00a0<a href=\"https:\/\/www.reproductivefacts.org\/\" target=\"_blank\" rel=\"noopener\">American Society for Reproductive Medicine<\/a>\u00a0notes it offers little added benefit when sperm parameters are already normal.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-64154b1f sc_fly_static elementor-widget elementor-widget-text-editor\" data-id=\"64154b1f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3 style=\"text-align: left;\">\u00a0<\/h3><p style=\"text-align: center;\">\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d9589b4 sc_fly_static elementor-widget elementor-widget-html\" data-id=\"d9589b4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<table border=\"1\" style=\"border-collapse: collapse;

In practice, most Bangkok clinics, GFC included, offer ICSI as the standard method, so pricing is quoted per ICSI package (at GFC, <strong>\u0e3f150,000\u2013\u0e3f350,000<\/strong>) rather than as IVF-vs-ICSI. See the full cost breakdown and packages on the\u00a0<a href=\"https:\/\/genesisfertility.co.th\/en\/services\/ivficsi\/\" target=\"_blank\" rel=\"noopener\">ICSI treatment page<\/a>.<\/p><p><b>Generally,<\/b> both IVF and ICSI procedures start from 100,000 Baht and can go up to 300,000 Baht or more. Prices vary depending on whether you choose a private hospital, a government hospital, or a specialized fertility clinic.<\/p><p><b>Note: <\/b>ICSI is typically more expensive than traditional IVF. This is because ICSI involves a much more complex and delicate laboratory process requiring highly skilled embryologists and specialized micromanipulation equipment.<\/p><p>While ICSI offers a higher fertilization success rate, standard IVF carries a higher risk of total fertilization failure since the sperm must navigate into the egg completely on their own.<\/p><h2 data-path-to-node=\"23\">Understanding Success Rates: ICSI vs. IVF<\/h2><p data-path-to-node=\"24\">When comparing fertilization rates, <b>ICSI typically yields slightly higher results than IVF<\/b>, with an average of about 70% of retrieved eggs successfully fertilizing. However, once fertilization is achieved, the ultimate clinical pregnancy success rates between ICSI and IVF are quite similar\u2014generally ranging between <b data-path-to-node=\"24\" data-index-in-node=\"317\">40% to 70%<\/b>.<\/p><p data-path-to-node=\"25\">Success depends on various factors, including underlying fertility conditions and the physical readiness of both partners.

Because eggs are fragile, there is a minor risk of egg damage from the needle insertion. Choosing a high-standard clinic with an exceptional laboratory and experienced specialists greatly minimizes this risk. Furthermore, some research suggests comparing the risks of chromosomal abnormalities, autism, or intellectual disabilities between assisted reproductive technologies and natural conception requires careful medical evaluation, with advanced laboratory screening often helping to mitigate risks.<\/p><h2>Frequently Asked Questions<\/h2><p><strong>How is ICSI different from IVF?<\/strong><\/p><p>In IVF, sperm fertilise the egg on their own in a dish. In ICSI, a single sperm is injected directly into the egg. Everything else is the same. ICSI is chosen when sperm quality is a concern or when embryos will be genetically tested.<\/p><p><strong>Is ICSI better than IVF?<\/strong><\/p><p>Not universally. ICSI is better for male-factor infertility and cases needing PGT-A. When sperm quality is normal, conventional IVF can be equally effective, and ICSI is not routinely needed.<\/p><p><strong>Is ICSI safer than IVF?<\/strong><\/p><p>Both have similar safety profiles. ICSI adds one lab step \u2014 injecting the egg \u2014 which carries a small chance of egg damage, but no meaningful added risk to the mother. The main risks (multiple pregnancy, preterm birth) are shared by both methods and are reduced by single embryo transfer.<\/p><p><strong>What are the main risks of IVF and ICSI?<\/strong><\/p><p>The main risks are shared by both: multiple pregnancy if more than one embryo is transferred, a related chance of preterm birth or low birth weight, and a small increase in birth defects that research ties mainly to the underlying infertility rather than the technique. Overall, both are considered safe.<\/p><p><strong>Does ICSI cost more than IVF?<\/strong><\/p><p>Slightly, due to the extra embryology work. At most Bangkok clinics ICSI is the default method, so it&#8217;s priced as a package \u2014 see the\u00a0<a href=\"https:\/\/genesisfertility.co.th\/en\/icsi-bangkok-guide\/\" target=\"_blank\" rel=\"noopener\">ICSI in Bangkok guide<\/a>\u00a0for ranges.<\/p><p><strong>Which should I choose \u2014 IUI, IVF or ICSI?<\/strong><\/p><p>It depends on the cause and severity of infertility, sperm quality, and age. Milder cases may start with IUI; male-factor or more complex cases go straight to ICSI.
