The use of fertility drugs

Support for fertility treatment: Medication during treatment

Fertility treatment is accompanied by medication. After we have examined you, we determine your exact treatment plan and the associated medication. Through regular monitoring and check-ups, we ensure that the medication is well tolerated and the treatment can be continued without complaints.


Clomifen / Letrozol Treatment

If we believe that these drugs will have a good effect on your fertility treatment, we will use them, as they stimulate the ovaries and trigger egg development.


GnRH analogues for down-regulation

To increase the chances of successful artificial insemination, natural hormone secretion is suppressed during the cycle. With so-called down-regulation, you will be given GnRH analogues. Depending on the individual treatment, the modes of action of the medications are distinguished as follows:

  • GnRH agonists: These medications are used for a long protocol. They initially stimulate production of the fertility hormones FSH and LH. After some time, the pituitary gland is fatigued by the production and ceases production. When these drugs are used, the precycle is started on about the 20th day of the cycle.
  • GnRH antagonists: With a short protocol, we rely on the effect of antagonists. These inhibit secretion of fertility hormones directly in the pituitary gland and therefore show an effect immediately after the first injection. Premature ovulation is thus prevented.


Gonadotropins: Hormone injections for egg maturation

Gonadotropins are hormones that promote egg maturation. These include the follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Administering these fertility drugs increases the chances that multiple fertile eggs will mature in the ovaries.


Human chorionic gonadotropin (hCG) – triggering of ovulation

Once enough eggs have matured, we can trigger ovulation as part of the treatment. The hormone hCG will be administered to you in the form of an injection. About 35 hours after the medication has been administered, ovulation takes place – and egg extraction after that.


Second half of the cycle: Progesterone to build up the uterine lining

Progesterone, the so-called yellow body hormone, is administered in the second half of the cycle. This prepares the uterine lining for implantation of the embryo. You can administer the medication yourself at home. To do this, you insert a suppository or gel into the vagina on a daily basis. Upon request, you can also have the hormone administered by injection.
