How to screen sperm for artificial insemination?

When a couple is preparing to have a baby, they may not be able to conceive for various reasons. For example, if there is a problem with the woman's fallopian tube, it is easy to cause the sperm to not combine with the egg, or the fertilized egg to not enter the uterus and implant. Another possible reason may be that the man's sperm is abnormal. In response to this series of problems, people now choose to do in vitro fertilization, which is the so-called artificial insemination. In the process of artificial insemination, it is very important to select the man's sperm of good quality. The specific method is as follows.

How to screen sperm for artificial insemination?

After 3-7 days of abstinence, semen can be obtained by masturbation. For obstructive azoospermia, semen can be obtained by epididymal or testicular puncture for examination and treatment. The semen of the donor comes from the frozen semen in the sperm bank.

Semen processing is mainly to achieve the required active sperm density, remove dead sperm, white blood cells, antibodies and other components in seminal plasma and semen, reduce the viscosity of semen, promote sperm capacitation, and improve sperm fertilization ability.

Factors that affect the success rate of artificial insemination:

First of all, the physiological age of women will affect the success rate of artificial insemination. Because the age of women determines the quality of eggs. Generally speaking, as women age, the quality of eggs will decline, and the success rate of artificial insemination will also show a downward trend. Therefore, women's age is one of the factors that affect artificial insemination. Therefore, experts recommend that women should not be over 30 years old when doing artificial insemination, so that the pregnancy rate will be good, and those over 35 years old are prone to fetal malformations.

Secondly, the cause of the patient's infertility is also a major factor affecting the success rate of artificial insemination. Generally speaking, the failure rate of artificial insemination treatment is also high for older patients with primary infertility, patients with severe uterine malformations such as endometriosis and polycystic ovary syndrome, patients with severe oligospermia and azoospermia who cannot obtain sperm from the testicles, or patients with a large number of deformed sperm, or patients with malformed or abnormally developed eggs.

Thirdly, female ovulation disorders will also affect the success rate of artificial insemination. Female ovulation disorders are an important factor affecting the success rate of artificial insemination. Ovulation disorders are a common disease among infertility symptoms. For patients with ovulation disorders, ovulation induction therapy and intrauterine artificial insemination are usually used for combined treatment, and the success rate is much higher than other infertility symptoms.

Fourth, psychological state plays an important role in the success rate of artificial insemination. Many data show that the patient's psychological and mental state is an important factor affecting the success or failure of IVF treatment.
