The World Health Organization defines infertility as a couple who have lived together for more than one year and have not conceived under normal conjugal life. Female factors cause 60% of infertility, male factors cause 30% of infertility, and both male and female factors cause 10% of infertility. The causes of infertility include: 1. Inflammation caused by cold during menstruation, menstrual and personal hygiene problems, and intercourse during menstruation in women, which leads to menstrual disorders and affects ovarian function with ovulation disorders, inducing infertility; 2. In men, masturbation or inflammatory infections are not thoroughly treated, leading to sperm discharge disorders and semen abnormalities, laying the foundation for infertility.
