Advertisements
उत्तर १
- Cryptorchidism: Failure of descend of testis from the abdomen in the scrotum
- Oligospermia: Low sperm count
- Asthenospermia: Decreased motility of sperm
- Hormone Imbalance: Decrease testosterone and excessive estradiol secretion (from adrenal glands) leading to virilism
- Infection: Like orchiditis (Inflammation of testis)
- Impotency: Failure of erection
उत्तर २
- Poor sperm production, which may result in too few sperm cells (oligospermia), lack of sperm mobility, or sperms that are deformed or dead.
- Blockage of the tubes between the testes and seminal vesicles, which may be caused by infection or other issues.
- Insufficient or defective fluid from the prostate that is unable to sustain live sperm.
- Other factors such as cryptorchidism (undescended testes), hyperthermia (high temperature in the scrotal sac due to tight undergarments), blockage of vas deferens, alcoholism, infection with mumps virus after puberty, deficiency of gonadotropins, ejaculation defects, and exposure to radiation.
These causes affect sperm quality, quantity, or delivery, leading to male infertility.
