Ovulation Induction

Ovulation induction (OI) refers to the use of fertility drugs to induce ovulation in a woman who does not ovulate herself. 

Fertility drugs used include tablets such as Clomid, Tamoxifen or Letrozole, or injections of the hormones Follicle Stimulating Hormone (FSH) or Luteinizing Hormone (LH). These may also be used in women who are already ovulating themselves in order to ‘boost’ ovulation, a process that is referred to as superovulation.

Monitoring ovulation

The dose of fertility drug used is critical and varies from woman to woman. Some women may over-respond to a particular dose while others may not respond at all. Close monitoring of developing follicles, which contain the eggs, is critical. This is done with transvaginal ultrasound scanning.

Once the follicles reach the correct size (around 20mm), ovulation is likely to occur within 48 hours. The couple are advised to have intercourse over the following days.
