Ovulation Induction with Follicular Monitoring

This is one of the simplest first-line treatment options in a couple seeking treatment for infertility.

Here, we aim to induce ovulation by giving medicines to boost the production of eggs in the ovary and monitor the response by means of a follicular study.

Treatment steps


Basal scan to rule out any cysts on day 2 or 3 of periods


Ovulation induction medicines are given to stimulate the growth of one or more follicles.


Follicular monitoring scan started on day 10 or 11 of cycle


HCG injection is given to help release the egg from the follicle once it becomes mature


Common medicines used are

  • Clomiphene citrate
  • Letrozole
  • Gonadotropin injections

In some cases and especially with the use of injections, we may form 2-3 follicles rather than one. This in turn may increase the possibility of multiple pregnancies.

The response to stimulation is monitored by a transvaginal scan called a follicular study started on day 10 or 11 of periods and repeated once in a few days to track the growth of the follicle, ending the study with the release of the egg from the follicle.

Once the follicle reaches a certain size of a minimum of 18-20 mm, in case the egg is not released. Spontaneously, we may give an injection of hCG to allow the egg to get released.

The couple can continue with their regular sex life if they have frequent sex. In case they have sex infrequently, we advise them to have more sex around the time of follicular growth or ovulation in order to increase the chance of getting pregnant.

The pregnancy happens naturally and in this treatment, we are just ensuring that things are happening as they are supposed to.

The average chances of getting pregnant in one month will range from 10-20% depending on the cause of infertility, age of the couple, number of eggs formed, any associated problems in the couple, etc.
