Those who have never been pregnant without contraception after marriage are called primary infertility; those who have been pregnant without contraception and have been infertile for two consecutive years are called secondary infertility. The cause of infertility may be in the female partner or in the male partner or in both men and women. The female factor accounts for 60%, the male factor accounts for 30%, and the male and female factors account for 10%.
