As mentioned, different treatments can be indicated. Among these: artificial insemination and in vitro fertilization.
Sperm is artificially inseminated directly in the woman (inside the uterus), or sperm of the spouse (IAC) when it has erection problems, if the sperm is not not fertile enough, in case of a problem related to the cervical mucus of the woman ...; or using the sperm of an anonymous donor (IAD) if that of the spouse turns out to be infertile.
For her part, the woman follows a treatment by ovarian stimulation to promote the maturation and the expulsion of eggs, and thus to promote fertilization.
When it comes to that of the spouse, sperm is directly introduced into the uterus of the woman at the time of ovulation. When it comes to a donor, the sperm is frozen and kept in sperm banks. The rules are very strict. The donor undergoes a complete medical examination for possible health problems. Careful investigations are carried out, including a search for possible infection with certain viruses, and in particular that of AIDS and hepatitis B.
This method is quite conclusive since the chances of success of getting a pregnancy is 18 to 15% per cycle, with however a risk of twin pregnancy, even triple. If after a few cycles, you do not get pregnant, it is advisable to use another method of medical assistance procreation (AMP).
In vitro fertilization
This solution is particularly suitable when the uterine tubes are obstructed (for various reasons), but it may have other indications, such as a fertility problem in humans (sperm not enough).
This technique requires two teams of practitioners; biologists on the one hand, and gynecologists on the other. It consists of putting an egg and spermatozoa in a "test tube" (hence the term in vitro ), and not in the uterus of women. Once the sperm is introduced into the egg, the division of the egg is expected, then the embryo is transferred to the uterus. This one must develop as for a normal pregnancy.
IVF goes very methodically:
> Ovarian stimulation. On the third day of the cycle, hormones are given to stimulate the follicles. Once ripe, ovulation is triggered by another hormone injection (HCG).
> The puncture. Under local anesthesia, the mature oocytes are removed by means of a small tube and a needle which is introduced through the vagina. This intervention can be a little painful. It allows the follicular fluid to be punctured and placed in a glass tube at a temperature of 37 ° C.
The sperm is taken a few hours earlier (or thawed the same day), and the sperm are separated from the seminal fluid and stored at 37 ° C.
> Fertilization. A few hours later, spermatozoa and oocytes are put together in a nutritious liquid for two days at body temperature; fertilization must occur at that time. The egg then begins to divide, it can be transferred into the uterus of the woman. All embryos fail to become established firmly. It is for this reason that the gynecologist usually carries out the "transfer" of two to three embryos. With this method, there is about 15 to 20% chance of getting pregnant.You want to react, to give your testimony or to ask a question?
