Girl or boy? Gender selection in Switzerland
Boy or girl? Anyone who wants a baby, above all, wants it healthy. Switzerland now allows a new technique with which gender can be selected.
The sperm determines the gender of a child. The woman's ovum always carries an X chromosome. If a sperm cell fertilizes the egg, the two merge into either an XX or XY combination. It depends on the sperm, whether the offspring is a boy or a girl.
There are numerous tips on how to select the gender at the desired child. Diet, time of ovulation or position in sex should have an impact on it.
As of July, there is now a technology in Switzerland for the first time, called MicroSort, which allows gender selection even before conception. The sperm are dyed and separated according to sex. The sorted sperm is then used in artificial insemination.
The question of whether it should become a boy or a girl is relevant, above all, in the case of gender-dependent or gender-limited genetic diseases. Because more than 500 - as well as Duchenne muscular dystrophy and hemophilia - seem to affect primarily or even exclusively members of one sex.
With the new method, parents can avoid transmitting these genetic diseases to their children. Another advantage, according to a study at the University Hospital Basel, is that the number of additional embryos that would otherwise be required for preimplantation genetic diagnosis can be reduced.
US studies have shown that around 93 percent of pregnant women who have conceived a girl have received a female child. The desire for a boy, it was almost 85 percent.
How does the gender selection procedure work?
Families who want to select the gender of their child, whether they have children or not, must first start IVF treatment. First, it ensures that the woman produces more than one egg in a regular period. For this, the patient is referred to a doctor in their home country for pretreatment.
After the appropriate treatment, the IVF treatment is started if there are no obstacles. Pretreatment begins on the 2nd or 3rd day of the woman's control period and is a medication treatment that lasts about 10 days. After the completion of the pre-treatment, the IVF and gender selection are started. For gender selection, the family will spend 1 week in the clinic. If it is desired to perform the entire treatment in clinic, it will take approximately 20 days and the planning should be done accordingly.
When choosing a gender, the following steps are performed with the series:
- Collection of eggs / eggs at the woman
- (OPU) Random fertilization of oocytes with semen samples of the spouse (micro-injection)
- Screening of good quality PGT embryos from the point of view of health and gender on the 3rd day of development
- Selection of healthy embryos of the desired gender on the 5th day of embryo development and transfer to the uterus of the mother
12 days after the embryo transfer, the woman's HCG hormone is examined to find out the pregnancy result.
From the point of view of gender selection, the IVF success rate is very high, especially in young patients (<35) because of the number of oocytes and the good quality. For postpartum pregnancies, 99% of the child's health and sex hit rate is correct.
The success rate of pregnancy after gender selection depends on the patient's age, fertility, oocyte reserve, number of healthy embryos, and the gender desired by the family.
What is gender selection?
Gender selection is a procedure used by couples who have a preference for a boy or a girl. The baby's sex can be determined after IVF treatment and genetic screening of the embryos.
In addition to gender selection, screenings for various genetic defects can be performed prior to implantation of healthy embryos into the woman. Thanks to PID (Preimplantation Genetic Diagnosis), not only can made the gender selection, but also be examined for gene disorders such as Down's Syndrome, Monosomy and Trisomy. Therefore, couples who desire gender selection can also ensure that their baby will not have genetic disease. This explains why PID is preferred by couples who want a healthy baby of their preferred gender.
IVF treatment is given to women who wish to be sexually selected. The oocytes are removed and fertilized with sperm via microinjection (ICSI). After fertilization, a genetic screening of the embryos is performed to implant only the healthy embryos of the desired sex. This enables the selection of the gender of the embryo and leads to a pregnancy with a baby of the chosen gender.
With PID, it is also possible to have numerical chromosomal abnormalities such as monosomy or trisomy (down syndrome, or trisomies), and single gene disorders (thalassemia, cystic fibrosis, hemophilia A1 and B1, muscular dystrophy, sickle cell anemia, Recklinghausen syndrome, Fanconi anemia ...) to determine in advance. PID can be used if there are inherited diseases related to the X chromosome and if medical gender selection is necessary.
