In about 30-35 percent of infertile couples male factor is the cause, either alone or in combination with some factor in female. In reproduction, male partner's work is the deposition of adequate and active number of sperms in the posterior vagina. Accordingly the main causes of infertility could be as under:-1. Production failure of sperms. 2. Sperms supply line failure. 3. Failure to deposit sperms in posterior fornix. 4. Secretions inimical to sperms. Most the cases are amenable to treatment, medically or surgically. In some cases artificial insemination by husband or donor sperm is necessary. In our country, some couple are not willing for insemination by donor sperm and opt for adoption.
