We all know that men's sperm motility is affected by external factors, so what are the factors that affect male reproduction in daily life?
Effect of high temperature on spermatogenesis
The scrotum is a temperature regulating organ. The optimal temperature is 35.5-36 ℃, which is 1-1.5 ℃ lower than the body temperature. It is a condition for spermatogenesis. If the temperature of the scrotum and testis increases, it can cause spermatogenesis disorders or low spermatogenic function, as well as spermatogenic arrest.
Tobacco and alcohol lead to decreased semen quality
Smoking can lead to decreased sperm activity and the presence of nicotine in semen, leading to infertility. Some infertile men are very sensitive to the toxins in tobacco, especially the spermatogenic cells, which are more susceptible to toxicity, resulting in delayed sperm growth, insufficient numbers, and reduced activity.
The impact of alcohol abuse on spermatogenesis. The toxicity of alcohol reduces testosterone levels, leading to low sperm quality.
Effects of radiation on spermatogenic cells
Testicles are the most sensitive to radiation, and germ cells are also very sensitive to radiation. Even low doses can lead to decreased sperm counts and temporary azoospermia.
Effects of metal elements on reproduction
"Human zinc is mainly concentrated in the testis, epididymis, and prostate gland. Zinc is related to sperm metabolism, sperm membrane stability, and sperm motility. Zinc deficiency can lead to male infertility.". There is a small number of sperm and poor semen quality. In addition, metal elements such as cadmium, lead, and copper have an impact on reproduction.
Varicocele and spermatogenic disorders
Varicocele can cause testicular blood circulation disorders, hemodynamic changes, and changes in the microenvironment of cells, which can hinder the normal material exchange of the seminiferous tubules, promote the degeneration or shedding of spermatogenic epithelium, and disorder the arrangement of spermatocytes and sperm cells. In severe cases, spermatogonia are lost, with only supporting cells remaining and multinucleated white blood cells visible.
