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 10 of such causative factors of low sperm count in men.
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.
Sperm production or function can be affected by overexposure to certain environmental elements, including:
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.
Radiation or x-rays
Exposure to radiation can reduce sperm production. It is being reported that keeping mobile phones in the pocket, close to the upper thigh, is extremely deleterious to sperm production with resulting low sperm count and morphology.
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.
Certain occupations might be linked with a risk of infertility, including welding or those associated with prolonged sitting, such as truck driving. However, the data to support these associations are inconsistent.
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.
Bisphenol A, an additive to plastics found in many household products, can lower sperm count and motility.
Cancers and nonmalignant tumours can affect the male reproductive organs directly, through the glands that release hormones related to reproduction, such as the pituitary gland, or through unknown causes. Surgery, radiation or chemotherapy to treat tumours can also affect male fertility.
