Thin semen

Introduction Semen refers to semen as thin as water, which is a milky white liquid, which is a kind of oligozoospermia. Generally, oligozoospermia is divided into idiopathic oligozoospermia, primary oligozoospermia and secondary oligozoospermia. Idiopathic oligospermia accounts for 11%-15% of infertile people. The number of sperm in semen is lower than that of a normal fertile male. The International Health Organization stipulates that male sperm should be no less than 20 million per milliliter. If it is less than 20 million, it will be classified as oligozoospermia. It will have a big impact.

Cause

Common factors are: idiopathic sperm reduction, long-term injection of androgen, due to negative feedback, hypothalamic gonadotropin-releasing hormone, resulting in decreased gonadotropin secretion, resulting in reduced or lack of sperm, drug effects, can be directly or indirectly Affects sperm production, such as sulfa drugs, furantan, spironolactone, cyclophosphamide, methotrexate, colchicine; radiation exposure, most sensitive to naive cells, including spermatogenic epithelium, can cause sperm cell division Hysteresis or cessation, or even irreversible damage; other factors, alcoholism, excessive smoking, drugs can inhibit sperm production, chronic prostatitis, varicocele, etc. can inhibit sperm production.

The scrotum cooling testicle is specially used to make sperm. The koji tube is very sensitive to temperature changes. The suitable temperature for this part is 2~3°C lower than the body temperature. The overheating inhibits the survival and maturation of sperm, resulting in the reduction of sperm count or activity in semen. reduce.

Endocrine disorders can improve sperm by regulating endocrine. Depending on the circumstances, intramuscular injection of urinary gonadotropin, chorionic hormone, testosterone eleven.

1. Abstinence 3 ~ 7d, semen routine analysis more than 3 times, sperm density is less than 20 million and can not find any cause, can be considered as idiopathic oligozoospermia. When the sperm density is l × 10 / mL, it can be diagnosed as severe oligozoospermia.

2. By asking about medical history, physical examination and other laboratory-assisted examinations (genetic examination, endocrine hormone determination, microbiological examination, anti-sperm antibodies, trace element determination, etc.), most of the causes of oligozoospermia can be found. Semen can be diagnosed as secondary oligozoospermia when it is analyzed for sperm with a small cause of disease.

Differential diagnosis

Less semen: Normal men's semen discharged by ejaculation is 2 to 6 ml. When the amount of semen is less than 2 ml, it can be confirmed that the semen is too small, but it should be noted that less semen does not mean less sperm.

Sperm quality decline: sperm quality decline means that the number of sperm, survival rate and activity capacity, density, etc. are reduced at the same volume level.
