Ovulation induction (OI) is drug treatment to induce ovulation in women with irregular or absent cycles.
It can involve taking pills or giving subcutaneous injections of drugs (the way diabetics receive insulin). It nearly always involves blood tests and ultrasound scans to monitor progress, both to time intercourse and to reduce the chance of multiple pregnancy.
Usually the couple has intercourse when ovulation is predicted or triggered by the ovulatory hormone (LH) injection, but artificial insemination using partner's sperm can be used, especially if the drugs affect the ability of sperm to make their way through the woman's cervix.
The major risk for this treatment is multiple pregnancy.
