Menopur is a fertility medication that is not designed to stop a menstrual period. Instead, it is used to stimulate the ovaries to produce multiple eggs for ovulation induction or controlled ovarian stimulation in assisted reproductive technology cycles [1]. It contains follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are gonadotropins that promote the development of ovarian follicles [1].
How does Menopur work to stimulate ovulation?
Menopur works by mimicking the natural hormones FSH and LH that are produced by the pituitary gland. FSH stimulates the growth and maturation of ovarian follicles, which are the sacs within the ovaries that contain eggs. LH plays a role in the final maturation of the follicles and triggers ovulation, the release of an egg from the ovary [1]. By administering Menopur, healthcare providers can control and enhance the follicular development process.
When is Menopur typically prescribed?
Menopur is prescribed to individuals undergoing fertility treatments, such as in vitro fertilization (IVF) or intrauterine insemination (IUI) [1]. It is used when a person's ovaries are not producing enough eggs naturally or when there is a need to produce multiple eggs for a higher chance of successful conception. It is not a treatment for menstrual irregularities themselves but rather a tool to augment ovulation for reproductive purposes.
What are the potential side effects of Menopur?
Common side effects associated with Menopur use can include injection site reactions such as redness, swelling, or bruising. Other potential side effects may involve abdominal pain, nausea, vomiting, diarrhea, headache, and bloating [2]. A more serious but less common risk is Ovarian Hyperstimulation Syndrome (OHSS), characterized by enlarged ovaries and fluid buildup in the abdomen and chest, which requires medical attention [2].
How is Menopur administered and monitored?
Menopur is typically administered via subcutaneous injection daily for a period determined by a healthcare professional, usually ranging from 7 to 12 days [1]. Treatment is closely monitored through regular ultrasounds to track follicle growth and blood tests to measure hormone levels, particularly estrogen. This monitoring helps adjust the dosage and determine the optimal time for triggering ovulation, often with a different medication like hCG [1].
