Understand In Vitro Fertilisation & Intra Cytoplasmic Sperm Injection (ICSI)
In Vitro Fertilisation (IVF) and Intra Cytoplasmic Sperm Injection (ICSI) are advanced procedures that have enabled many individuals and couples to fulfill their dreams of parenthood. Gaining knowledge about these treatments not only helps in understanding the processes involved but also empowers you to make informed choices on your path to becoming parents. In this section, we provide you with comprehensive insights into both IVF and ICSI, detailing how they work, their effectiveness, and what to expect during the treatment journey.
In Vitro Fertilization, commonly known as IVF, is a fertility treatment where an egg is fertilised by sperm outside of the body. The process involves stimulating the ovaries to produce multiple eggs, retrieving these eggs from the ovaries, combining them with sperm in a laboratory to facilitate fertilisation, and then transferring the resulting embryos back into the uterus.
Intracytoplasmic Sperm Injection (ICSI) is a specialized form of IVF that is used primarily for the treatment of severe cases of male-factor infertility. ICSI involves the injection of a single sperm directly into a mature egg. This process increases the chances of fertilization by bypassing the initial stages of natural fertilisation that can be challenging for some sperm.
IVF can be an invaluable solution for many fertility issues, including blocked or damaged fallopian tubes, male factor infertility, endometriosis, ovulatory disorders, or unexplained infertility. It's also useful for those using donor eggs or sperm, or for women who wish to freeze their eggs or embryos for future use.
IVF enhances conception chances by overcoming many fertility barriers. By fertilising the egg outside the body, IVF bypasses potential issues such as blocked fallopian tubes or low sperm mobility. Moreover, doctors can select the best quality embryos for transfer, further improving the odds of a successful pregnancy.
The IVF process can be physically and emotionally intense. During IVF stimulation, individuals might experience a certain level of discomfort or even mild pain. The process often requires self-administration of daily injections, which could cause discomfort at the injection site. Hormonal medications can cause side effects such as bloating, mood swings, and fatigue. The egg retrieval is usually done under sedation, so it's not typically painful. The embryo transfer is often described as similar to a Pap smear. Emotionally, IVF can bring a mix of hope, anxiety, and anticipation.
Deciding if IVF is the right choice depends on your individual fertility issues, age, health, personal circumstances, and financial situation. Discussing these factors with your healthcare provider or fertility specialist can help guide this important decision.
The success rate of In Vitro Fertilisation (IVF) varies based on factors like the woman's age, the cause of infertility, and the quality of eggs and sperm. For women under 35 using their own eggs, the live birth rate per cycle is typically 40% to 50%. This rate decreases with age, particularly after 40. Quality of embryos transferred also influences success rates. These are average rates, and individual outcomes can significantly vary. Always consult your healthcare provider or fertility specialist.
What it is, how does it work, and who can it help?
A Step-by-Step Guide to in Vitro Fertilisation (IVF) Procedure
Step 1: Ovarian Stimulation
The first stage of IVF involves ovarian stimulation, where you'll be given hormonal medications to encourage your ovaries to produce multiple eggs, rather than the single egg typically released each month. This usually involves self-administering injections over a period of about 8-14 days.
Step 2: Egg Retrieval
Once your eggs are mature, a procedure is scheduled to retrieve them. Under light sedation, a needle is guided via ultrasound through the vagina and into each ovary, where the mature eggs are gently aspirated. Despite the minimally invasive nature of this procedure, it's typically not painful due to the sedation provided.
Step 3: Fertilisation and ICSI
Post-retrieval, your eggs are fertilised with sperm in a laboratory setting. If normal fertilisation is not likely due to lower sperm quality or quantity, a technique called Intracytoplasmic Sperm Injection (ICSI) may be employed, where a single sperm is injected directly into each egg.
Step 4: Embryo Culture
Following successful fertilisation, the embryos are cultured in the lab for a few days. This allows embryologists to monitor their development and select the most viable ones for transfer.
Step 4: Embryo Transfer
The final step is the embryo transfer, typically done a few days after egg retrieval. A thin catheter is used to transfer one or two selected embryos directly into the uterus. This procedure is generally not painful and is similar to having a smear test.
Following the transfer, there's a wait of about two weeks before a pregnancy test is taken to confirm whether the IVF has been successful.
