Ovulation Induction (OI)

Ovulation Induction is a simple process to encourage your eggs to release, so you maximise your chance of conception. It’s suitable for women who are producing low levels of hormones for ovulation, or who are not ovulating at all.  You’ll take medication (as tablets) to stimulate your hormones.

How does Ovulation Induction work?

First, we’ll confirm your ovulation cycle by:

  • Taking blood samples to measure hormone levels at specific stages of your cycle
  • Carrying out a transvaginal ultrasound to see the development of follicles in the ovaries, and the thickness and appearance of the lining of the womb.

If you go ahead with ovulation induction, a medication called clomiphene citrate induces ovulation by causing eggs to develop in the ovaries and be released. We may also use artificial hormone preparations of follicle stimulating hormone (FSH) to encourage the development of one or more follicles and therefore more than one egg.

Clomiphene may be used in conjunction with timed intercourse, or intrauterine insemination (IUI) to ensure that the sperm are introduced at the right time.

We’ll monitor your cycle more closely than a natural cycle, using:

  • vaginal ultrasounds to check follicle development
  • blood tests and urine tests to observe hormone levels.

We may also use an injection, human chorionic gonadotropin (known as hCG) to trigger the process of ovulation if it does not occur spontaneously.
