Had sex for seven years without any protection, always pulling out, and never had an accidental pregnancy.

Patient's question:

No

Doctor's answer:

Couples of childbearing age living together for more than one year, with normal sexual life, who have never taken any contraceptive measures and fail to conceive are referred to as infertility. Infertility is divided into two types: primary infertility and secondary infertility. Infertility caused by miscarriage is called secondary infertility. Fertilization is a complex physiological process.
