Couples who have lived together for more than a year and have regular sexual intercourse without using any contraception and still have not conceived are diagnosed with infertility. For men, it is referred to as sterility. Infertility requires couples to visit the reproductive medicine department for relevant infertility tests. The tests for men are simpler, primarily requiring abstinence from sexual activity for two to seven days before undergoing a semen analysis. For women, the tests vary depending on the condition but generally include the following aspects: First, blood tests related to endocrinology are conducted 2 to 4 days into menstruation. Second, from 3 to 7 days after menstruation ends, during which sexual intercourse should be avoided, tests can be conducted to check the patency of the fallopian tubes. Third, ovulation can be monitored by ultrasound from days 9 to 11 of the menstrual cycle until ovulation is confirmed. Additionally, routine gynecological examinations, including checks of the cervix and ultrasound examinations, are also conducted.
