Miss Yang has been married for over two years, and her marital relationship has always been good. Her husband is also in good health. No matter how hard the couple worked for 2 years, Miss Yang couldn't get pregnant. Miss Yang thought that infertility must be her problem, and treating infertility was never troublesome because she believed her husband's body was absolutely normal. However, the doctor went to see her and took the medicine repeatedly, but she couldn't see any movement in her stomach. Later, when her husband accompanied Miss Yang to the hospital for treatment, the doctor insisted that her husband undergo a semen test. Miss Yang's mother-in-law looked displeased and said, "My son has never had any illness or taken any medicine. The examination results diagnosed Miss Yang's husband as oligozoospermia, and at this time, he thought he was strong and cheerful, and regretted it deeply.
Oligospermia is a common condition of male infertility. Spermatozoa are produced in the testis, and go through spermatogonium, primary spermatocyte, secondary spermatocyte, and spermatids in the seminiferous tubules of the testis, and finally form mature sperm, which are released into the seminiferous tubules. It is a continuous process, which lasts about 64 to 72 days in the seminiferous tubules. Throughout the process of sperm formation, it is regulated by endocrine hormones, and any factors that affect spermatogenic function will lead to a decrease in sperm count.
These conditions can lead to oligospermia:
1. Varicocele: When varicocele occurs, it causes an increase in the local temperature of the testicles and vasoactive substances, thereby affecting testicular spermatogenic function. However, the degree of varicocele is not proportional to sperm quality.
2. Endocrine abnormalities: The normal spermatogenic function of men depends on the normal function of the hypothalamus pituitary gonad axis. Any link obstacle will affect the spermatogenic function. Other diseases such as thyroid and adrenal gland diseases will also affect the function of the gonad, resulting in oligospermia.
3. urinary system infection: chronic infection of accessory gonad can affect various laboratory indicators in semen.
4. Autoimmunity: Reproductive immunology research has found that male autoimmunity can affect fertility, while anti sperm antibodies can affect the production and transportation of sperm.
5. Cryptorchidism: Cryptorchidism is one of the important factors affecting semen quality. About 60% of patients with unilateral cryptorchidism are infertile, so if sperm density is low and cryptorchidism is present, early treatment is necessary.
6. Chromosome abnormalities: Chromosome abnormalities have a serious impact on sperm density, motility, and morphology.
7. Others: Excessive scrotal temperature, radiation damage, chemical drugs, and drug effects can all cause oligospermia.
