What Is ICSI and How Does It Differ from IVF?
ICSI, or Intracytoplasmic Sperm Injection, is an advanced form of in vitro fertilization (IVF) that involves directly injecting a single sperm into an egg to facilitate fertilization. Unlike traditional IVF, where the sperm & egg are simply placed together in a petri dish and left to fertilize naturally, ICSI takes a more hands-on approach by manually inserting the sperm into the egg.
While both IVF and ICSI are methods of assisted reproduction, the main distinction lies in the level of intervention required. In a typical IVF procedure, sperm is placed in close proximity to the egg and is left to fertilize on its own. However, in cases where male infertility factors are present—such as low sperm count, poor sperm motility, or abnormal sperm morphology—ICSI may be used to maximize the chances of fertilization.
Why Is ICSI Used?
ICSI was developed to help men with severe fertility issues, such as:
- Low sperm count (Oligospermia): When the male partner has a very low number of sperm, making it difficult for any sperm to reach and fertilize the egg naturally.
- Poor sperm motility (Asthenozoospermia): When sperm are sluggish or unable to swim efficiently toward the egg.
- Abnormal sperm morphology (Teratozoospermia): When sperm have an unusual shape or structure that makes it difficult for them to penetrate the egg.
- Previous IVF failure: You might face problems with fertilization if your previous IVF attempts failed.
- Sperm retrieval from non-ejaculatory sources: In cases where sperm is extracted directly from the testes or epididymis due to an obstruction or absence of sperm in the semen.
In cases of female infertility, ICSI can also be employed if other methods of fertilization have proven unsuccessful. It is particularly helpful for women undergoing IVF with egg donors, where sperm quality is the primary challenge.
The ICSI Treatment Procedure: Step-by-Step
The ICSI treatment procedure is a detailed and precise process that involves several key steps, each of which plays a vital role in ensuring the best possible chances of successful fertilization.
Step 1: Ovulation Stimulation
The first step in the ICSI procedure, as with traditional IVF, is ovulation stimulation. The woman undergoes hormone therapy to stimulate her ovaries to produce multiple eggs. This is typically done using injectable hormones like FSH (follicle-stimulating hormone) and LH (luteinizing hormone). The goal is to encourage the ovaries to produce several mature eggs, which will be retrieved later for fertilization.
Throughout this process, OBGYN specialists closely monitor the woman’s response to the medication through blood tests and ultrasound scans. The stimulation phase generally lasts around 10 to 14 days, after which the eggs are ready to be collected.
Step 2: Egg Retrieval
Egg retrieval, also known as aspiration, is the following stage after the eggs reach maturity. This is a minimally invasive procedure done under light sedation. A fine needle is inserted through the vaginal wall into the ovaries, where the eggs are located. The eggs are then carefully suctioned out.
The egg retrieval is a delicate procedure that requires precision, and the collected eggs are immediately placed in a culture medium for fertilization.
Step 3: Sperm Collection and Preparation
In parallel, the male partner provides a sperm sample. If there are any issues with sperm quality, sperm may be retrieved directly from the testes or epididymis using a small surgical procedure. Once the sperm sample is obtained, it is washed and prepared in the laboratory to isolate the healthiest, most motile sperm.
Step 4: Sperm Injection (ICSI)
The hallmark of the ICSI treatment procedure is the sperm injection process. In the laboratory, a skilled embryologist uses a micromanipulator to inject a single sperm directly into the cytoplasm of each mature egg. This is done under a microscope, and the sperm is carefully selected based on its morphology and motility.
This step bypasses many of the natural barriers to fertilization, making ICSI a highly effective option when sperm quality is a concern. The egg and sperm are then cultured together in a controlled environment, and the embryologist monitors the fertilization process closely.
Step 5: Embryo Culture and Monitoring
After the sperm is injected into the egg, the fertilized eggs (now embryos) are kept in an incubator for observation. The embryos are monitored for signs of development over the next few days. The embryologist checks for the early stages of division, and by day 3 or 5, healthy embryos that show signs of development are ready for transfer.
In some cases, genetic testing of embryos may also be conducted during this stage to screen for any inherited conditions.
Step 6: Embryo Transfer
The final step in the ICSI treatment procedure is the embryo transfer. This is a non-invasive procedure, and no anesthesia is required. The goal is for the embryos to implant in the uterine lining and begin developing into a pregnancy.
Following the transfer, the woman is monitored for signs of pregnancy, and a blood test is usually performed around 10-14 days later to confirm whether implantation has occurred.
Success Rates of ICSI Treatment
ICSI has a high success rate, particularly in cases where male infertility is the primary factor. The chances of success depend on several factors, including the woman’s age, the quality of the eggs and sperm, and the overall health of the couple. On average, the success rates for ICSI are comparable to those of traditional IVF, with many couples achieving successful pregnancies after their first attempt. However, it is important to remember that results can vary from case to case.
In India, ICSI has become one of the most popular and effective treatments for couples experiencing infertility. With the country’s advanced reproductive technologies, skilled embryologists, and affordable fertility care, many couples are turning to ICSI as a solution to their fertility challenges.
