According to experts, a normal male ejaculates 2-6 milliliters of semen per ejaculation, and less than 2 milliliters is considered oligospermia, also known as oligospermia. Insufficient semen can affect the quality and quantity of natural sperm, leading to low male fertility. The main causes of male infertility caused by oligospermia are:
1、 Genital tract infections:
It can affect various laboratory indicators in semen.
2、 Chromosome abnormalities:
Chromosome aberration has a serious impact on sperm density, motility, and morphology; 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.
3、 Autoimmunity:
Reproductive immunology research has found that male autoimmune diseases can affect fertility, while anti sperm antibodies can affect the production and transportation of sperm. Genital tract infection: chronic infection of accessory gonad can affect various laboratory indicators in semen.
4、 Cryptorchidism:
Cryptorchidism is one of the important reasons affecting semen quality. About 60% of patients with unilateral cryptorchidism are infertile. Therefore, if sperm density is low and cryptorchidism exists, early treatment is necessary.
5、 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 gonad function and cause oligospermia.
6、 Varicocele:
When varicocele occurs, it causes an increase in the local temperature of the testicles and vasoactive substances, thereby affecting the testicular spermatogenic function. But the degree of varicocele is not proportional to the quality of sperm.
