Study Notes
Fertility Drugs: Mechanism of Action and Ovulation Stimulation
Fertility drugs are a group of pharmaceuticals used by women who face difficulty conceiving naturally due to irregular menstrual cycles, ovulatory disorders, or other fertility issues. These medications aim to help regulate hormonal activity, support follicle growth, and increase the likelihood of successful pregnancy. The main types of fertility drugs are Clomiphene Citrate and Gonadotropins. Let's explore their mechanisms of action and how they stimulate ovulation.
Clomiphene Citrate
Clomiphene is often the first line treatment for ovulatory dysfunction because it has been proven effective and safe over many years. It works primarily by blocking estrogen receptors in the brain, which tricks the body into thinking there isn’t enough estrogen causing the hypothalamus and pituitary gland to produce more follicle-stimulating hormone (FSH) and luteinizing hormone (LH). This increased production of hormones triggers egg development and maturation leading to the release of mature eggs during ovulation.
However, clomiphene does have side effects such as hot flashes, mood changes, and multiple births due to its ability to stimulate both ovaries simultaneously. Pregnant patients with diabetes should avoid taking this medication unless it is a last resort since high blood sugar levels can cross the placenta and affect fetal health.
Gonadotropins
Gonadotropins are injectable fertility treatments composed of human menopausal gonadotropins (hMG), also known as Pergoveris®, Repronex®, and Menogon®, or Choriogonadotropin Alfa, better recognized as Pregnyl® or Profasi®. These medications directly mimic the natural hormones produced by the pituitary gland: FSH and LH. They encourage the ovarian follicles to grow and develop into fully mature eggs ready for potential fertilization.
The administration of these hormones may cause some minor discomfort at the injection site—a common issue when using any injectable drug. Additionally, like clomiphene, multiple pregnancies are possible if too many eggs are released during ovulation. For this reason, doctors carefully monitor the patient throughout the process to ensure optimal results while minimizing risks.
In conclusion, fertility drugs play a crucial role in assisting couples facing conception challenges. By understanding their mechanisms of action and potential benefits and drawbacks, patients can make informed decisions about their choice of medication and work closely with healthcare providers to optimize chances of success.
