Ovulation Induction Treatment

When is it done?

Approximately 20% - 25% of patients who consult for sterility have alterations in ovulation such as in delayed ovulations and/or infrequent or complete lack of ovulation. Therefore, these patients present an irregular or even inexistent menstruation. In these cases, ovulation induction treatments would proceed if the remaining explorations of the male (seminogram) and the woman (echography and/or hysterosalpingography) are confirmed to be normal.

In sterile women who ovulate regularly but who must undergo artificial insemination, light ovulation stimulant treatments are usually used to increase the possibilities of pregnancy too.


What is the treatment like?

Ovulation Induction treatment requires the administration of hormone preparations which are applied subcutaneously with schedules that depend on the type of anovulation. These treatments require periodic echographic and blood tests controls throughout the ovulatory cycle.

Are there different types of treatment?

There are two types of hormone treatments:

  1. Patients with type I anovulation: There are two types of hormone preparations which are subcutaneously administered.

  2. Patients with type II anovulation: Most of the cases correspond to patients with a polycystic ovary syndrome. In these cases oral clomiphene and subcutaneous FSH are used.


How long does this treatment last?

It is recommended to repeat the ovulation induction during a period ranging from 4 to 6 months. If pregnancy is not achieved, then Invitro or laparoscopic fertilisation techniques are indicated.

What are the possibilities of achieving pregnancy?

The possibilities of achieving pregnancy range from 15 % to 20 %.
