Normally when we undergo Artificial Insemination (AI) we use three types of drugs.
The first one is a gonadotropin (follitropin alpha, biosimilar follitropin alpha, follitropin beta, menotropin...) whose approximate cost adjusted to the dose of artificial insemination would be around 200 € (10 days of treatment). Its function would be the growth of follicles. In the case of artificial insemination, the objective is a single follicle of adequate growth, therefore the doses used are low (approximately 75 IU).
Secondly, we need a medication that triggers ovulation when follicular growth is optimal (called Ovitrelle), whose approximate cost would be around 60 €. It is estimated that a follicle has reached optimal follicular growth to trigger ovulation, when it measures 18-22 mm.
Thirdly, it may be necessary (although not in all cases of artificial insemination) to inhibit ovulation during the treatment, so that it does not occur before the end of the treatment. This last drug is called an antagonist and its approximate cost is about 200 € (5 days of treatment).
