IVF or in vitro fertilization has undoubtedly altered countless lives for the better by helping couples conceive and fulfill their dream of giving birth to and bringing up a child of their own. In recent times, hormonal imbalance and health-and lifestyle-related issues have increased infertility rates globally among men as well as women. IVF Success rates have considerably improved in different parts of the world at far more affordable rates.
In the event that more and more couples want to opt for IVF treatment. However, it is important to be fully aware of what IVF is, how the treatment is done, and who is a likely candidate for IVF. One of the most frequently asked first questions is about the best age for IVF. People also ask where and when to go for IVF treatment and about the best type of IVF treatment to opt for. We look at these details as well as the success rate and the types of IVF treatment available to help make an informed decision.
Candidates for IVF
- Women who have tried for a long time to get pregnant but have been unable to do so may be advised to opt for injectable medications, intrauterine insemination (IUI), or other alternatives.
- If these conventional therapies do not work to help a woman conceive, IVF is advisable, particularly if there are certain underlying conditions responsible for the difficulty in getting pregnant.
- Women with ovulation dysfunction, blocked Fallopian tubes, PID (pelvic inflammatory disease), PCOS (polycystic ovary syndrome), endometriosis, uterine problems, or problems relating to cervical mucus are typically advised to opt for IVF if they fail to conceive.
- Couples with male factor infertility issues, such as low sperm count, also undergo IVF when they fail to conceive.
Hence, it is important to arrive at a definitive diagnosis for the reasons behind the difficulty of getting pregnant and then choose the right course of action.
If you are contemplating undergoing an IVF procedure, you should understand exactly how this works. This helps you get a realistic idea of the chance of success of the IVF process, which involves several steps. Here is what you can expect:
- Ovulation induction: It is the first step of the IVF process. This involves monitoring of the ovaries, the release of the egg, and its timing. The fertility doctor will ensure that the hormone levels are at optimal levels. It is seen that the ovaries are producing eggs as needed. If the ovaries are not producing requisite eggs, fertility-boosting medications help stimulate the ovaries to ovulate and produce eggs. With the help of this, the ovaries produce several eggs within a short period.
- Egg retrieval: Egg retrieval is the second step. After administering pain medication, a thin needle is inserted into the vaginal wall. With the help of ultrasound, fluid is extracted, and then the egg (oocyte) is isolated from that fluid. This is transferred to a culture dish and then to an incubator.
- Fertilization and embryo culture: Now it is time for the fertilization of the egg with the sperm. The sperm sample may be from a partner, a volunteer, or a sperm donor. The most active sperm is brought into contact with the egg either in a special chamber or by direct injection into the egg.
- Embryo formation: The subsequent process of embryo formation is closely monitored. The quality of the embryos is assessed to rule out any disorders or abnormalities. The healthiest and strongest embryos are identified for transfer.
- Embryo transfer: The last step of the IVF procedure is embryo transfer and implantation. The sturdiest embryos are then transferred via the cervix into the uterus for implantation. This is followed by a complete bed rest to give the woman the best chance at conception.
- Types of IVF Treatment: There are various types of IVF treatments. Each case is assessed independently to decide on the best course or a combination of treatments based on the underlying cause of infertility. Different types of fertility treatments are recommended. The decision is made considering the medical condition, the age, and the health of the couple, as well as certain lifestyle factors.
- The types of IVF cycles: The natural cycle is the simplest type of IVF cycle. It does not stimulate the ovaries for egg production. The ovaries produce eggs as they would in the natural course, which are collected and mixed with sperm to create embryos. This is a good option if there are no abnormalities in the ovaries or the Fallopian tubes and the woman is ovulating normally each month. However, if this is not the case, ovarian stimulation may be required. This uses hormonal medications to stimulate the ovaries to produce several eggs to increase the chances of conception. Only mild stimulation may be used in cases where there is the apprehension of ovarian hyperstimulation syndrome (especially among women who have already undergone IVF treatments previously).
Different types of fertility treatments
- IVF with Laser-Assisted Hatching: In IVF, laser-assisted hatching is used in cases where the hatching of the egg is difficult, typically due to thicker-than-usual embryo walls. This procedure is used to help the fertilized egg attach to the walls of the uterus. Acid or mechanical hatching procedures are some other procedures that may be used in some cases.
- IVF with Egg Donation: In the case where a woman is unable to produce eggs or cannot produce eggs of a sufficiently healthy quality, IVF with egg donation may be opted for. The eggs from a donor woman are combined with the sperm of the man. The resultant embryos are implanted into the uterus of the woman who is undergoing IVF treatment. Therefore, in this case, the woman would carry a child that is not biologically her own. The sperm could be sourced from her own partner or a donor. She would nurture the embryo in her uterus and carry the fetus to term.
- IVF with ICSI: IVF with Intracytoplasmic Sperm Injection (ICSI) is typically used when the male partner displays male factor infertility. The main difference here is the method of fertilization. In IVF, the egg and sperm are merged in a petri dish and fertilization is achieved naturally. With ICSI, however, a single sperm is injected into the cytoplasm of the egg using a very fine needle. In cases of very severe male factor infertility, the sperm of a donor is used. That is, the child would not biologically be that of the male partner.
- IVF with ICSI and Optical Spindle View: It may be recommended to increase the chances of a successful pregnancy. Here, the mitotic spindle within the woman's egg is examined to gauge quality. The spindle helps in the chromosomal division of the egg. The embryos are minutely examined to detect any possible abnormalities. It also helps ensure that there is no damage around the site of the injection.
- IVF with ICSI and Testicular Biopsy: IVF and ICSI with testicular biopsy are yet another of the different types of fertility treatments that may be recommended if the male partner's testicular function is a problem. In cases where the quality of the male sperm is seen to be deteriorated or of poor quality, the sperm is surgically extracted (as opposed to being collected via ejaculation) and then merged with the egg. Different types of IVF cycles and various permutations and combinations may be used depending upon each couple's particular set of circumstances.
Success Rate for IVF
The chance of successful IVF is greatest for women younger than 35 (approximately 35% chance for live birth). As age increases, however, the chance of success becomes progressively lower (approximately 31% chance at 35-7; approximately 21% for 38-40; approximately 11% for 41-42; and approximately 5% after 43 years). That said, advancements in reproductive medicine have improved outcomes for older women; overall health, lifestyle, and causes of infertility can influence these results; using success calculators, which assess medical and lifestyle parameters, may be useful in estimating personal probabilities of success or rates of success, and providing direction for choosing a course of treatment.
Conclusion
Understanding IVF success rates is one component; emotional, physical, financial and multiple births potential are also issues for couples to consider prior to treatment; the variability in success between individuals necessitates careful planning and the assistance of experts; maintaining good overall health and addressing any issues will additionally improve the possibility of success; ultimately, both a personalised treatment plan and the setting of realistic expectations are essential for achieving your goals with IVF.
