1. Semen cannot pass through the vascular duct, which is caused by a narrowing or clogged semen duct.
2. The testicle is unable to produce sperm naturally, has premature deterioration, or has an infection with mumps down the testicle and the testicle is swollen and inflamed. The mumps infection destroys the spermatogenesis process since childhood.
3. The pituitary gland is unable to produce hormones to stimulate the testicles, making the testicles unable to produce sperm.
4. Too little semen secretion which can cause infertility. May be caused by problems with the reproductive system causing less semen secretion or caused by erectile dysfunction.
5. Abnormal semen is usually caused by abnormal pH components of semen, these symptoms will result in unnatural sperm motility, slow, weak, and easy to die.
