<\/span><\/div>What is IVF-ICSI and how does it differ from conventional IVF?<\/h2><\/div>In Vitro Fertilization (IVF) is a process where the union of the egg and sperm occurs outside the body, in our specialized laboratory here in Donostia.<\/p>\n
\n- Conventional IVF:<\/strong> The retrieved eggs are placed in a culture dish along with a processed semen sample, allowing the sperm to fertilize the eggs naturally.<\/li>\n
- IVF-ICSI:<\/strong> We go one step further. Using a high-powered microscope and micromanipulators, our team of embryologists selects a single sperm and microinjects it directly into the interior of each mature egg retrieved. <\/li>\n<\/ul>\n
This technique circumvents possible barriers that prevent the sperm from penetrating the egg by itself, being an effective solution in many cases of infertility.<\/p>\n<\/div>
For whom is IVF-ICSI indicated?<\/h2><\/h3><\/div>The IVF-ICSI technique is especially beneficial and is recommended in situations such as:<\/p>\n<\/div>
- <\/i><\/span>\n
Tubal factor<\/strong>: When the fallopian tubes are blocked, damaged or absent (for example, after tubal ligation or salpingectomy). IVF allows bypassing the tubes, joining egg and sperm directly in the laboratory. <\/p>\n<\/div><\/li>- <\/i><\/span>\n
Endometriosis:<\/strong> Especially in moderate or severe degrees, or when previous treatments have been unsuccessful. Endometriosis can affect ovarian quality, tubal function or implantation. <\/p>\n<\/div><\/li>- <\/i><\/span>\n
Ovarian Factor \/ Anovulation:<\/strong> Women with ovulation problems (such as Polycystic Ovarian Syndrome – PCOS) who have not achieved pregnancy with simpler treatments such as ovulation induction or artificial insemination.<\/p>\n<\/div><\/li>- <\/i><\/span>\n
Uterine Factor:<\/strong> Some uterine conditions that may hinder natural conception.<\/p>\n<\/div><\/li>- <\/i><\/span>\n
Infertility of Unknown Origin (IOD):<\/strong> When no clear cause is found after studying both partners and pregnancy has not been achieved after a reasonable time or with simpler treatments (such as Artificial Insemination).<\/p>\n<\/div><\/li>- <\/i><\/span>Mild, Moderate or Severe Male Factor:<\/b> If semen parameters (concentration, motility, morphology) are altered, but it is considered that the sperm still have sufficient capacity to fertilize the egg. However, if there are doubts or a history of low fertilization, ICSI is often chosen to ensure fertilization.<\/div><\/li>
- <\/i><\/span>\n
Advanced Maternal Age: When the ovarian reserve or egg quality decreases due to age, IVF can maximize the chances by obtaining several eggs and selecting the best embryos.<\/p>\n<\/div><\/li><\/ul>
A personalized evaluation by our team in Donostia-San Sebastian<\/strong> is essential to determine if IVF-ICSI is the most appropriate option for you.<\/p>\n<\/div><\/div><\/div>
