What is Low sperm Count or oligozoospermia? Pregnancy refers to a fertility male sperm in the number of is lower than normal a disease, that is, less male semen. International Health Organization stipulates that the male sperm per milliliter of not less than 20 million if less than 20 million on the classified as oligospermia, fertility will have a great impact. Oligozoospermia is a common male disease, one of the causes of male infertility. Oligozoospermia may be congenital, there may be some of the body caused by changes in the quality of the disease, such as prostatitis, epididymitis, testicular disease.
Causes of oligozoospermia
The main causes of oligozoospermia disease factors, such as varicocele, cryptorchidism, urinary tract infection, low autoimmune, drug factors, sexual life too frequently, nutritional deficiencies, physical factors, specifically lead to oligozoospermia The reason is:
Disease factors:
(1) varicocele: varicocele, the testis will increase the local temperature, vasoactive substances increased, thus affecting the testicular spermatogenesis, resulting in an insufficient number of sperm. But the degree of varicocele and sperm quality disproportionate.
(2) cryptorchidism: cryptorchidism is one of the important reasons affecting the quality of semen. Unilateral cryptorchidism about 60% of patients infertility, so if the sperm density is low, there is cryptorchidism, must be treated early.
(3) urinary tract infection: persistent gonadal infection, such as orchitis, epididymitis, prostatitis, seminal vesiculitis, this inflammation can cause a reduction in the number of sperm, resulting in oligozoospermia.
(4) autoimmune reduction: reproductive immunology study found that male autoimmune can affect fertility, anti-sperm antibodies can affect the sperm production and delivery.
(5) endocrine dysfunction: male normal sperm function depends on the hypothalamus – pituitary-gonadal axis function of normal, any one of the links, will affect the spermatogenic function, such as thyroid, an adrenal disease also affect the gonadal function Oligospermia.
(6) chromosome abnormalities: chromosome aberration on sperm density, activity rate and morphology have a serious impact.
Drug factors
Drug effects Drug effects can directly or indirectly affect sperm production, such as sulfonamides, furanantadine, spironolactone, cyclophosphamide, methotrexate, colchicine.
sexual life too frequent
Excessive consumption of men’s physical and semen, long-term will lead to physical decline in men, less semen produced, causing oligozoospermia.
physical factors:
Radiation-irradiated radiation is most sensitive to immature cells, including spermatogenic epithelium, which can cause Low sperm Count cell division to hinder or stop, or even cause irreversible damage.
Nutritional deficiencies:
Trace elements lack zinc, vitamin E deficiency is also an important cause of less refined.
Other factors:
Including alcoholism, excessive smoking, drugs, etc. can inhibit sperm production.
