OI (Ovulation Induction) is a treatment option used almost exclusively in women who do not ovulate, or ovulate irregularly and unpredictably.

Two examples of women who possibly require OI are women with Polycystic Ovarian Syndrome (PCOS), and women with a diagnosis of hypogonadotrophic hypogonadism (essentially when the brain and ovary are not communicating). Both these groups of women may present with infrequent or absent periods.

OI requires the use of either a tablet called Clomephine, or injectable Follicle Stimulating Hormone (FSH). The decision regarding which option is best for you is reliant on history, examination and blood hormone levels which will be performed as part of initial consultation. It is extremely important to monitor OI closely with blood testing and pelvic ultrasound scanning to minimise chance of multiple pregnancy (twins or more).

If ovulation is your only issue limiting your fertility, then intervention to induce ovulation is associated with a very good chance of a pregnancy.

Couples will proceed with this intervention for a variable length of time – this decision needs to be made on clinical information as well as the thoughts of the couple I am treating. There is little evidence that OI for a woman who already ovulates is helpful, and a recent study suggests that some types of OI may slightly decrease chance of pregnancy – again your personal situation needs to be assessed to ensure appropriate treatment options are discussed.
