Ovulation Induction (OI)


Ovulation Induction (OI) may be recommended for women who rarely or never ovulate but have normal tubes and have a partner with a normal semen analysis. 

OI involves taking medication, there are two methods that can be used: fertility tablets (clomiphene citrate) 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 couple are advised to have intercourse.
