In which cases is in vitro fertilization recommended?
In vitro fertilization is not an assisted reproduction treatment suitable for all cases, so it is essential to know when recommended.
Invitro fertilization is suitable for:
- Women with blocked fallopian tubes.
- Women who have been sterilized in the past now want to conceive again.
- Patients with the absence of the fallopian boxes.
- In severe cases of endometriosis.
- When the quality of the ovules affects reproduction naturally or if there is a limited number of them, for example, in advanced age.
- If other assisted reproductive treatments have previously failed.
- If the man suffers from low sperm count or mobility problems with it.
- When a woman wants to get pregnant using a sperm donor.
How is the in vitro fertilization procedure
The IVF is a process by which they are joined in a laboratory mature oocytes of a woman with the sperm of a man after a few days, transfer the best embryos to the uterus to be implemented, and produce gestation.
This complex process has several steps:
- Ovarian stimulation
Through the application of fertility drugs, usually in the form of injections, the production of the ovaries is stimulated so that, instead of giving rise to an egg as they would naturally, several oocytes are produced to obtain a more significant number of embryos and thus guarantee a better success rate in the process. During this phase, blood tests and transvaginal echoes can be performed to monitor the evolution of the process.
- Removal of mature eggs
When it is considered that the eggs have reached the ideal size and state, then they are extracted through a minor and outpatient surgery known as follicular aspiration. This procedure, which takes about 15 minutes, is performed with the patient sedated.
- Fertilization of the ovules
A semen sample is also collected from the couple or obtained from the chosen donor. When the eggs have been extracted, the fertilization or fertilization process must begin. For this, the eggs and sperm are placed in a controlled chamber to fertilize the egg, a process that usually occurs within a few hours.
If the possibility of fertilization is suspected to be below, then the sperm can be injected directly into the egg, a process known as ICSI. In some cases, both methods are used to ensure adequate fertilization.
- Embryo culture
Once the ovum has been fertilized, it will divide and become an embryo. This process is observed for several days. The sources are classified according to their quality; those that divide actively are reserved, while those blocked or do not continue division are discarded.
- Embryo transfer
About five days after the eggs have been retrieved, it is time to place the embryos in the mother’s uterus. This process is performed with a cannula and in an outpatient procedure that does not require anesthesia. It is common for several embryos to be introduced to guarantee a greater probability of pregnancy; however, when doing so, candidates must be aware of the possibility of multiple pregnancies.
Those embryos that have not been used will be reserved for a new procedure if gestation does not occur.
- Checking the pregnancy status
About 15 days later, it will be checked whether or not there is a pregnancy. If the embryo (s) introduced into the uterus have adequately implanted, then the hormone hCG levels will increase, indicating that the pregnancy has begun.
Pros of in vitro fertilization
- They offer an alternative to couples who wish to conceive a biological child but cannot do so due to various gynecological conditions or specific problems with male sperm.
- Because quality embryos that have not been transferred to the woman are preserved, there is a possibility of using them in future treatment to try again if another child is desired or if the procedure did not work in the first place.
- The success rate of this procedure is considered high, generally hovering around 60% and rising to 80% in women who have undergone three fertilization attempts. If the process is done with eggs from a young donor, the success rate may be higher.
- It is considered a minimally invasive assisted reproduction technique, so the woman will not suffer any physical damage.
Cons of in vitro fertilization
- It is an expensive process, and without reimbursement, the invested money is not returned if the gestation does not occur.
- The success rate is not guaranteed and depends on multiple factors such as the donor’s age, the quality of the eggs, the quality of the sperm, etc.
- There is an excellent risk of multiple pregnancies, so parents must have the emotional and monetary availability to deal with the situation. Additionally, pregnancies of this type are riskier for the mother and fetuses, so they must be carefully monitored.
Deciding to undergo in vitro fertilization implies, like any process, advantages and disadvantages, so it is recommended to have good medical advice to discover if it is the suitable alternative for those interested.
