In vitro fertilization
In vitro fertilization is an assisted reproduction technique widely used in infertility cases. It was popularly known as the "test tube baby" technique. This is a process in which eggs are fertilized by sperm outside the woman's body, in vitro, which in Latin means "in glass".
In vitro fertilization is as follows:
The woman receives special reproductive hormones to favor the development of several eggs;
Final egg maturation is induced by the administration of another hormone;
After 36 hours, the fluid containing the eggs is removed from the ovaries with a needle. This procedure is usually done with the sedated woman and the doctor uses an ultrasound to guide the needle to the ovary;
The collected eggs are then mixed with the man sperm, which has already been washed and concentrated;
Eggs and sperm are left in an incubator at 37 ° C for 24 hours for fertilization to take place;
During this time, only one of many sperm will penetrate and fertilize the egg;
After fertilization, the cells will divide and multiply to form an embryo;
After 2 or 3 days, a healthy embryo will have 8 cells. It is then transferred to the uterus through a thin, flexible tube where it is left to implant and generate a pregnancy;
After 12 to 14 days, it is already possible to know the result through the beta-hCG pregnancy test.
Explanation: The booklet clearly states that Emergency contraceptive medications do not provide protection against sexually transmitted diseases (STD’s).
