Mechanisms & Repurposing/Human menopausal gonadotropin (hMG)

FSH + LH activity gonadotropin mixture

Human menopausal gonadotropin (hMG)

Urinary FSH/LH preparation used to stimulate follicular development in labelled fertility protocols.

EndocrineReceptor agonism

Primary Mechanism of Action

Clinical / Scientific

hMG contains FSH and LH activity, stimulating granulosa-cell aromatase and thecal androgen supply (two-cell two-gonadotropin model) during controlled ovarian stimulation when labelled products are used.

Pathway Targets

FSH receptor

Scientific explanation

Follicular recruitment and aromatase induction.

LH receptor

Scientific explanation

Thecal androgen / luteal support depending on preparation.

Pathway Convergence

In Plain Language

hMG is a mix of FSH and LH activity, the two pituitary hormones that grow ovarian follicles in fertility treatment.
