Menotropins

From PeptidePlaza, the free peptide reference · Entry #1213 · Anti-Aging · Sources fetched 2026-09-11 · Editorial standards

Menotropins is a anti-aging research peptide. Menotropins, also known as Menopur, is a gonadotropin and a luteinizing hormone/choriogonadotropin receptor agonist and follicle stimulating hormone receptor agonist.

Menotropins is an FDA-approved gonadotropin that functions as an agonist for both the luteinizing hormone/choriogonadotropin receptor and the follicle stimulating hormone receptor. It is indicated for the development of multiple follicles and pregnancy in ovulatory women as part of an Assisted Reproductive Technology (ART) cycle. First approved in 1975, it is also studied for conditions such as infertility, polycystic ovary syndrome, and hypogonadism. Research on menotropins includes reviews on its role in superovulation for ovulatory infertility and its association with early miscarriage and fetal malformations after ovulation induction.

6 Safety and risk profile

6.1 Regulatory status

Menotropins is currently classified as FDA approved. Approval applies to specific clinical indications and dosing; research-grade material is not the approved product.

6.2 Contraindications

Conditions and populations in which use is contraindicated:

  • Prior hypersensitivity to MENOPUR or menotropins products or one of their excipients
  • High levels of FSH indicating primary ovarian failure
  • Pregnancy
  • Presence of uncontrolled non-gonadal endocrinopathies (e.g., thyroid, adrenal, or pituitary disorders)
  • Sex hormone dependent tumors of the reproductive tract and accessory organs
  • Tumors of pituitary gland or hypothalamus
  • Abnormal uterine bleeding of undetermined origin
  • Ovarian cyst or enlargement of undetermined origin, not due to polycystic ovary syndrome

6.3 Long-term risks

  • Ovarian Hyperstimulation Syndrome (OHSS)
  • Pulmonary and Vascular Complications
  • Ovarian Torsion
  • Multi-fetal Gestation and Birth
  • Ovarian Neoplasms

7 Frequently asked questions

What is Menotropins used for?
Menotropins is indicated for the development of multiple follicles and pregnancy in ovulatory women as part of an Assisted Reproductive Technology (ART) cycle. It is also studied for conditions such as infertility, polycystic ovary syndrome, hypogonadism, azoospermia, and Kallmann Syndrome.
How does Menotropins work?
Menotropins acts as a luteinizing hormone/choriogonadotropin receptor agonist and a follicle stimulating hormone receptor agonist. This mechanism helps stimulate ovarian function, leading to the development of multiple follicles in women undergoing fertility treatments.
Is Menotropins FDA approved?
Yes, Menotropins is an FDA-approved gonadotropin. It received its first approval in 1975 and is marketed under names such as Menopur.
What are the side effects of Menotropins?
Common side effects of Menotropins include abdominal cramps, abdominal pain, headache, and injection site pain. More serious adverse reactions can include abnormal ovarian enlargement, ovarian hyperstimulation syndrome (OHSS), thromboembolic events, and multi-fetal gestation.
What are the contraindications for Menotropins?
Menotropins is contraindicated in women with prior hypersensitivity to the product, high FSH levels indicating primary ovarian failure, pregnancy, uncontrolled non-gonadal endocrinopathies, sex hormone dependent tumors, tumors of the pituitary gland or hypothalamus, abnormal uterine bleeding of undetermined origin, or ovarian cysts or enlargement not due to polycystic ovary syndrome.
What warnings are associated with Menotropins?
Menotropins should only be used by physicians experienced in infertility treatment. It can cause Ovarian Hyperstimulation Syndrome (OHSS) with or without pulmonary or vascular complications, and multiple births. Careful monitoring of ovarian response and serum estradiol levels is crucial to minimize risks.
