Subzonal Insemination (Suv)

Subzonal Insemination (Suv) is a method of artificial insemination that is used in cases where a woman’s infertility is caused by the inability of sperm to overcome the barrier surrounding the egg.

When using in vitro fertilization methods (fertilization outside the mother's body), several sperm (no more than six) are introduced through the zona pellucida directly into the vitelline space, which surrounds the egg shell. After some time, if the egg is successfully fertilized, the resulting blastocyst is implanted into the woman’s uterus.

This approach allows sperm to bypass natural barriers to the egg and increases the chances of successful fertilization in certain forms of infertility. Subzonal fertilization can be used in combination with other reproductive technologies.

Subzonal insemination (Suv) is a method of artificial insemination that is used in cases of infertility in women caused by the inability of sperm to cross the barrier around the egg. Subzonal fertilization takes place outside the mother's body and involves the introduction of several sperm into the vitelline region of the egg through the membrane pellucida. If fertilization occurs, the resulting blastocyst is then implanted into the mother's body.

The benefits of subzonal insemination include the ability to obtain more sperm to fertilize an egg and increase the chances of a successful conception. Additionally, this method may be more effective in treating infertility caused by male factors, such as sperm damage or poor sperm motility.

However, subzonal fertilization has its disadvantages. Firstly, it is a more expensive method than conventional in vitro fertilization. In addition, there is a risk of damage to the egg when sperm is injected, which can lead to unsuccessful conception. There is also the possibility that multiple sperm may penetrate the egg, which can cause multiple pregnancies.

Overall, subzonal insemination may be a useful treatment for infertility in some women. However, before undertaking this method, it is necessary to conduct a thorough examination and discuss all possible risks and benefits with your doctor.

In vitro fertilization is a new form of artificial insemination. In this way, maternal chromosomes can be replaced with paternal ones. During the procedure, a small amount of sperm containing two gametes is placed inside the follicle. The doctor irradiates it and the test tube, allowing ovulation to occur. Then, using a microscope, the fastest and strongest male gamete is introduced into the egg. After this, the procedure can be extended up to six days. Doctors pay attention to the fact that foreign male material can potentially negatively affect a woman’s body - for example, cause cancer or tissue damage. In addition, it will be possible to conceive a child in this way only after three to six months - this is how long it usually takes for a woman to become pregnant. If the procedure is successful, the woman is given an x-ray to ensure that the fertilized egg is ready for transfer.
