Timed intercourse

Timed intercourse means having sex in the fertile window, sometimes guided by ovulation tracking or clinic scans, and sometimes combined with ovulation induction medicines. It is the least invasive treatment and is often the first step for people with irregular ovulation and otherwise normal test results.
