Intracytoplasmic Sperm Injection (ICSI) is a specialized technique used in conjunction with in vitro fertilization (IVF) to enhance the fertilization process in cases of male factor infertility, where conventional methods of fertilization may be ineffective. ICSI involves the direct injection of a single sperm into an egg to facilitate fertilization. Here’s an overview of the ICSI procedure within the context of IVF:

The ICSI process begins with ovarian stimulation, similar to standard IVF. The woman undergoes hormone injections to stimulate the ovaries to produce multiple mature eggs. Once the eggs reach maturity, they are retrieved from the ovaries using a minimally invasive surgical procedure called transvaginal ultrasound-guided follicle aspiration.
On the day of egg retrieval, the male partner provides a semen sample through masturbation. In cases of severe male factor infertility, sperm may be obtained from a sperm donor or retrieved surgically from the testes (testicular sperm extraction, TESE). The sperm sample is processed in the laboratory through sperm washing to:
In the ICSI procedure, a single sperm is selected from the processed sperm sample and injected directly into each mature egg using a micromanipulation technique. This involves:
After the ICSI procedure, the injected eggs are cultured in the laboratory under controlled conditions to allow fertilization and embryo development. The embryos are monitored closely over the next few days to assess their quality and progression.
Typically, after 3-5 days of embryo culture, one or more high-quality embryos are selected for transfer into the woman’s uterus. The embryo transfer procedure is performed in the clinic without anesthesia. This involves:
Following embryo transfer, the woman may be prescribed progesterone supplements to support the luteal phase of the menstrual cycle and improve the chances of embryo implantation. Approximately two weeks after embryo transfer, the woman undergoes a pregnancy test to determine if implantation has occurred.
ICSI is highly effective in cases of severe male factor infertility, such as low sperm count, poor sperm motility, or abnormal sperm morphology, where conventional IVF may not result in successful fertilization. However, ICSI may also be used in other situations, such as previous IVF failure, unexplained infertility, or egg quality issues. Couples considering ICSI should discuss the potential benefits, risks, and success rates with their healthcare provider to determine if it is the right treatment option for their individual circumstances.
