A man’s fertility rate generally relies on the quantity and quality of his sperm. If the amount of sperm a man ejaculates is low or if the sperm is of poor quality, it will be difficult and sometimes impossible for him to impregnate a female.According to Prof. Oladapo Ashiru, a male infertility is usually caused by problems that affect either sperm production in the testes or sperm transport.See some factors that causes low sperm count in men.1.Prior surgeries:…Certain surgeries, including vasectomy, might prevent you from having sperm in your testicles. Inguinal hernia repairs, scrotal or testicular surgeries, prostate surgeries, and large abdominal surgeries performed for testicular and rectal cancers, among others, are also suspect. In most cases, surgery can be performed to either reverse these blockages or to retrieve sperm directly from the epididymis and testicles.2.Environmental causes
Sperm production or function can be affected by overexposure to certain environmental elements, including:
Industrial chemical;Extended exposure to benzenes, toluene, xylene, herbicides, pesticides, organic solvents, painting materials and lead might contribute to low sperm counts. Exposure to lead or other heavy metals also can cause infertility.3.Drug use/Alcohol:….Anabolic steroids taken to stimulate muscle strength and growth can cause the testicles to shrink and sperm production to decrease. Use of cocaine or marijuana might reduce the number and quality of your sperm as well. Alcohol can lower testosterone levels and cause decreased sperm production.4.Lifestyle
Men who smoke might have a lower sperm count than those who don’t smoke.Also, obesity can impair fertility in several ways, including directly impacting sperm and by causing hormone changes.
