Overview

HMG (human menopausal gonadotropin) is a gonadotropin preparation that provides follicle-stimulating hormone (FSH)– and luteinizing hormone (LH)–like activity. It has long-standing use in regulated reproductive and endocrine medicine.

In some catalogs and informal materials, HMG is also discussed in broader hormone-related or performance-oriented contexts, which may diverge from evidence-based fertility indications and local regulations.

Mechanism of action

HMG contains gonadotropin activity that can:

  • Stimulate ovarian follicular development through FSH-like actions
  • Support ovulation and sex-steroid production via LH-like actions
  • Influence testicular function and spermatogenesis in certain male endocrine contexts

The net effects depend on baseline endocrine status, concomitant therapies, and the carefully structured protocols used in reproductive medicine.

Indications and use context

In regulated care, HMG may be used in specific fertility and endocrine indications, such as controlled ovarian stimulation under specialist supervision. Precise indications, eligibility criteria, and labeling vary by product and jurisdiction.

Outside such settings, discussion of HMG in performance or non-fertility contexts should be approached cautiously. Use that diverges from evidence-based protocols can carry additional legal, ethical, and safety considerations.

Safety and side effects

High-level safety themes

Safety information for HMG is closely tied to its use in fertility and endocrine protocols and should always be interpreted with reference to official labeling and specialist guidance.

Reported risks and side effects can include ovarian hyperstimulation syndrome (OHSS), multiple pregnancy in fertility contexts, local injection-site reactions, and hormone-related symptoms such as bloating, mood changes, or breast tenderness.

Because outcomes depend heavily on patient selection, monitoring, and protocol design, decisions belong with clinicians experienced in reproductive or endocrine medicine.

Pharmacology and dosing considerations

HMG (Menotropin) contains both FSH and LH activity (1:1 ratio) and is used to stimulate follicle development or spermatogenesis.

Common administration patterns

Route: Subcutaneous injection or Intramuscular (IM).

Protocol structure and dosage:
  • Dosage: Typically 75 IU to 150 IU daily.
  • Duration: Administered for 7–12 days until follicles/levels are appropriate.
  • Monitoring: Requires frequent ultrasound and bloodwork monitoring to prevent overstimulation.

This information is based on standard fertility clinic protocols.

Formulations and combinations

HMG products are typically supplied as vials for reconstitution, sometimes used in combination with other reproductive hormones such as hCG as part of multi-step fertility regimens.

In this catalog, structural listings for HMG and related products are provided for organizational purposes only. They do not imply that specific combinations or regimens are recommended or appropriate outside specialist care.

Research and evidence snapshot

HMG has been studied in a range of fertility and endocrine indications, with outcomes that include ovulation rates, pregnancy rates, and endocrine marker changes. Over time, protocols and product choices have evolved alongside newer agents and refinement of assisted reproductive technologies.

Interpretation of HMG data requires close attention to study design, populations, and comparators. High-level summaries like this are not a substitute for specialized fertility guidelines or primary research.

Frequently asked questions

Future FAQs may address conceptual questions such as how HMG fits into modern fertility protocols, how clinicians mitigate the risk of OHSS, and how HMG compares with more targeted gonadotropin preparations. Answers will remain educational and non-prescriptive.
