What Is HMG (Human Menopausal Gonadotropin)?

HMG is a hormonal medication used to treat both female and male fertility disorders. It is a natural combination of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), two gonadotropins that are essential for reproductive function.

Mechanism of action

After injection, HMG is absorbed by muscle tissue and gradually released into the bloodstream. Unlike HCG, which stimulates almost exclusively LH receptors (Leydig cells), HMG acts more comprehensively by binding to both LH and FSH receptors

• LH → stimulates the production of endogenous testosterone

• FSH → promotes sperm maturation, Sertoli cell function, libido, and mood

For this reason, HMG is highly valued in fertility clinics, in male hormone replacement therapy (TRT), and in post-cycle recovery protocols.

Purpose and Use

Originally developed for the treatment of female infertility, HMG is now also widely used in men for:

• preserving testicular function during hormone therapy

• prevent or reduce testicular atrophy

• support spermatogenesis

• improve fertility recovery after prolonged cycles

In the world of sports and bodybuilding, HMG is often used in conjunction with HCG:

• HCG maintains LH stimulation

• HMG provides FSH, thereby completing testicular stimulation

Studies and meta-analyses indicate that the combination of HCG and HMG significantly improves hormonal recovery and fertility compared to the use of HCG alone.

Directions for Use (General Guidelines)

HMG should be used under medical supervision, as the response varies greatly from person to person.

General guidelines (not a substitute for medical advice):

• Testicular preservation during long cycles:
  75–150 IU of HMG 2–3 times a week ± HCG

• Post-Cycle Therapy (PCT):
  HMG + HCG to reactivate LH and FSH

• Hypogonadotropic hypogonadism:
  low, continuous doses for several months

Excessive use can lead to overstimulation of Leydig cells, so the dosage must always be adjusted accordingly.
