Asthenozoospermia, as the name suggests, refers to the loss of sperm vitality. Asthenozoospermia can seriously affect our fertility, and it can bring endless troubles to male friends. So, can asthenozoospermia be artificially fertilized? What are the causes of asthenozoospermia? Next, let's take a closer look and understand it thoroughly.
Can asthenozoospermia be artificially fertilized
One of the important causes of male infertility is asthenozoospermia. Many times, due to certain factors, the motility of sperm is directly affected, especially during forward movement, which prevents sperm from swimming to the specific location of the egg at the optimal time, thereby affecting fertilization. However, the success rate of artificial insemination for asthenozoospermia is also influenced by other factors, which require a physical examination to determine.
Firstly, ovulation induction. The success rate of intrauterine artificial insemination is approximately 10% -15% per cycle. If the patient has mild sperm abnormalities, ovulation should also be coordinated to stimulate the egg and increase the chances of pregnancy. A study once found that in 308 cycles of intrauterine artificial insemination, the pregnancy rate of eggs stimulated by ovulation is higher than that of natural cycles.
Secondly, age. The fertility of women will gradually decline with age, especially the ability of older women to conceive will significantly decrease. Therefore, the earlier women undergo artificial insemination at marriageable age, the higher their chances of getting pregnant
Thirdly, the timing of fertilization. Choosing the most appropriate timing for artificial insemination can also improve the success rate. Generally, the best time for fertilization is during a woman's ovulation period. Therefore, instruments can be used to detect the specific time of a woman's ovulation period, while observing cervical mucus and ovulation conditions, in order to fertilize at the best time.
What are the causes of asthenozoospermia
Firstly, abnormal semen liquefaction. The non liquefaction or high viscosity of semen is one of the causes of male infertility, and an important factor may be affecting the motility of sperm, leading to infertility. In semen that does not liquefy, slender fibrous proteins can be seen and interwoven with each other, reducing the space for sperm movement and restraining the sperm. At the same time, it can also be seen that coarse fibers are connected by many fine fibers to form a network, which may be the reason for mechanical limitations on sperm forward movement.
Secondly, immune factors. Anti sperm antibodies (AsAb) can affect the fertilization function of sperm through several different pathways. The impact on sperm vitality may be due to the binding of AsAb to the tail of sperm, which hinders sperm vitality, reduces motility, and has poor penetration ability. This has been confirmed by the significant decrease in the ability to penetrate cervical mucus when anti sperm antibodies are present at the tail of sperm. Some scholars have observed a so-called "shaking phenomenon" of sperm by using AsAb positive serum in contact with human sperm. The shaking phenomenon is mainly caused by the binding of anti sperm antibodies to the head and entire tail of the sperm, which inhibits the forward movement of the sperm, but there is no significant change in survival rate.
In summary, asthenozoospermia can be artificially fertilized, and the success rate varies from person to person. Male friends with asthenozoospermia should relax and not be too sad. Your family and friends will always support and accompany you. Friends who have bad habits of smoking and drinking should try to quit, as it is not good for their fertility.
