Ovulation Induction (OI)

Ovulation Induction (OI) is for women who may or may not ovulate regularly and who have normal fallopian tubes and male partners with regular sperm quality. The treatment involves stimulating the woman’s ovaries with ovarian stimulation medication and the follicular growth monitored with blood tests and possibly ultrasound scans for timed intercourse. This is a common first step along the fertility treatment journey.

OI involves taking medication, there are two methods that can be used: ovarian stimulation medications (Clomiphe Citrate Letrozole) or injections of follicle stimulating hormone (FSH).

Medication is used to stimulate a follicle on the ovary which contains the developing egg, sometimes more than one follicle will grow. The progress of the developing follicles is monitored by measuring the oestrogen hormone they produce using blood tests, and through watching them grow by ultrasound examination. When the size of the follicle and the oestrogen level suggests that the egg is soon to be released (ovulation) the client is advised to have intercourse.
