CAUSES OF INFERTILITY IN MALES:1) Hyposecretion of gonadotropic hormones FSH and LH.2) Improper development of sex organs.3) Bacterial or viral infections in the sex organs or STDs.4) Damage or blockage of vas-deferens.5) Oligospermia: Less sperm count in ejaculated semen, i.e., less than 20 millions sperms.6) Azoospermia: Absence of motile sperms in the semen.7) Asthenozoospermia: It is a condition of sperms without tail.8) Impotency: Inability to have or maintain erection of penis.9) Production of abnormal sperms.10) Round-headed sperm is produced due to the Golgi apparatus not transformed into acrosomes.11) Any damage or hyposecretion from secretory ducts results in reduced fertilization due to reduced movement of sperms in the acidic environment of the uterus. 12) Early ejaculation (discharge of semen before insertion of the penis into the vagina).
