What is HMG?

HMG (Human Menopausal Gonadotropin) is a purified gonadotropin preparation extracted from the urine of post-menopausal women — who produce elevated levels of FSH and LH due to the loss of negative feedback from ovarian oestrogen and inhibin following menopause. The resulting preparation contains both follicle-stimulating hormone (FSH) and luteinising hormone (LH) biological activity — typically in an approximately 1:1 ratio — making it a naturally derived dual gonadotropin research tool that mirrors the combined FSH/LH hormonal environment driving gonadal function in the intact hypothalamic-pituitary-gonadal (HPG) axis.

FSH and LH are glycoprotein hormones produced by pituitary gonadotroph cells in response to hypothalamic GnRH stimulation — sharing a common alpha subunit but with distinct beta subunits conferring receptor specificity. FSH acts through FSHR on ovarian granulosa cells and testicular Sertoli cells to drive follicle development, granulosa cell proliferation, aromatase expression, and oestrogen production in females — and spermatogenesis support in males. LH acts through LHR on ovarian theca cells and testicular Leydig cells to drive androgen production, and at mid-cycle in females triggers the LH surge responsible for ovulation and corpus luteum formation.

HMG’s combined FSH and LH activity makes it a research tool for studying the coordinated effects of both gonadotropin pathways on gonadal cell biology — providing a more physiologically representative hormonal stimulus than either recombinant FSH or LH alone in research applications where both receptor pathways are relevant to the experimental question. Its well-characterised gonadotropin activity profile and its historical role as the foundational clinical gonadotropin preparation have established it as a reference compound in reproductive endocrinology research across European laboratories.

What Does HMG Do in Research?

In laboratory settings, HMG is studied as a combined FSH/LH gonadotropin preparation with broad reproductive endocrinology research applications. EU and European researchers working with HMG typically focus on:

• FSH and LH receptor pharmacology — HMG provides simultaneous FSH receptor and LH receptor stimulation — making it a research tool for studying the coordinated downstream signalling of both gonadotropin receptor pathways in gonadal cell systems, including cAMP/PKA activation, steroidogenic enzyme induction, and cell proliferation responses.
• Folliculogenesis research — FSH drives follicular development through granulosa cell FSHR — stimulating granulosa cell proliferation, aromatase expression, oestrogen production, and FSH receptor upregulation across follicular development stages. HMG is used in folliculogenesis research to examine how combined FSH/LH stimulation influences follicular maturation biology compared to FSH alone.
• Steroidogenesis research — LH acts on theca cells and Leydig cells through LHR to drive androgen production via StAR protein induction and CYP17A1 enzyme activation. HMG provides both the FSH component driving aromatase-mediated oestrogen synthesis in granulosa/Sertoli cells and the LH component driving androgen substrate production in theca/Leydig cells — enabling research into the two-cell model of steroidogenesis and gonadal sex steroid production.
• Ovarian biology and granulosa cell research — studies use HMG to examine granulosa cell responses to combined gonadotropin stimulation — including oestradiol production, inhibin secretion, growth factor expression, and the molecular biology of granulosa cell differentiation across the follicular development process.
• Spermatogenesis and testicular biology — in male reproductive biology, HMG provides FSH activity driving Sertoli cell support of spermatogenesis alongside LH activity driving Leydig cell testosterone production — making it a research tool for studying the combined gonadotropin requirements of testicular function and the cellular biology of spermatogenesis support.
• Hypothalamic-pituitary-gonadal axis research — HMG is used as a peripheral gonadotropin stimulus in HPG axis research — enabling studies examining gonadal responses to gonadotropin stimulation, negative feedback mechanisms, and the physiological consequences of combined FSH/LH axis activation on downstream gonadal hormone production and reproductive biology.
• Ovulation biology research — the LH component of HMG contributes to research examining LH-driven ovulation mechanisms — including LH surge-triggered resumption of meiosis in oocytes, cumulus cell expansion, and the proteolytic cascade mediating follicle rupture. Combined FSH/LH stimulation protocols using HMG are used to model the hormonal environment of the periovulatory period.
• Corpus luteum biology — following ovulation, LH drives corpus luteum formation and progesterone production. HMG’s LH activity is used in research examining luteinisation biology — including the molecular transition from follicular granulosa cells to luteal cells and the steroidogenic shift from oestrogen to progesterone production.
• Gonadotropin receptor signalling research — both FSHR and LHR are leucine-rich repeat-containing GPCRs signalling through Gs-coupled cAMP/PKA pathways with additional signalling through ERK, PI3K/Akt, and other cascades. HMG is used in receptor signalling studies examining the downstream consequences of combined gonadotropin receptor activation in gonadal cell biology.
• Superovulation and controlled ovarian stimulation models — HMG is used in pre-clinical superovulation protocols — examining the biological consequences of supraphysiological gonadotropin stimulation on follicular development, oocyte quality, ovarian biology, and hormonal responses. These models are used in reproductive biology research examining the cellular and molecular responses to controlled ovarian stimulation.
• Comparative gonadotropin pharmacology — HMG is studied alongside recombinant FSH, recombinant LH, and recombinant HCG preparations to examine how the source, glycosylation profile, and FSH/LH ratio of gonadotropin preparations influence receptor activation, downstream signalling, and gonadal biological responses in comparative reproductive endocrinology research.
• Male hypogonadism models — studies have examined HMG in pre-clinical models of hypogonadotropic hypogonadism — characterising its ability to restore gonadal steroidogenesis and spermatogenesis in gonadotropin-deficient animal models — contributing to understanding of the gonadotropin requirements for male reproductive function restoration.

All research applications are for in vitro and pre-clinical use only.

What Do Studies Say About HMG?

HMG has an extensive research literature spanning reproductive endocrinology, gonadotropin receptor pharmacology, and reproductive biology — with decades of pre-clinical and clinical investigation establishing its biological profile and research utility.

Gonadotropin receptor biology: Studies using HMG and its purified FSH and LH components have comprehensively characterised FSHR and LHR receptor pharmacology — including receptor binding kinetics, downstream cAMP/PKA signalling cascades, and the gene expression programmes activated by gonadotropin receptor stimulation in granulosa, theca, Sertoli, and Leydig cell populations. This receptor biology literature provides the mechanistic foundation for interpreting HMG’s combined gonadotropin effects in research settings.

Folliculogenesis research: A large body of pre-clinical and clinical literature has characterised HMG’s effects on follicular development — documenting dose-dependent follicle recruitment, granulosa cell proliferation, oestradiol production, and follicular maturation parameters. These findings have established HMG as the reference combined gonadotropin preparation for folliculogenesis research and controlled ovarian stimulation biology.

Steroidogenesis studies: Studies examining HMG’s effects on gonadal steroidogenesis have characterised the two-cell model of ovarian steroid production — documenting LH-driven androgen production in theca cells and FSH-driven aromatase-mediated conversion to oestrogen in granulosa cells as complementary and interdependent processes. These mechanistic steroidogenesis findings have established HMG as a research tool for studying the coordinated gonadotropin requirements of ovarian sex steroid production.

Spermatogenesis research: Studies examining HMG in male reproductive biology have characterised its ability to support spermatogenesis through combined Sertoli cell FSH stimulation and Leydig cell LH-driven testosterone production — with findings in gonadotropin-deficient animal models documenting the relative contributions of FSH versus LH to different stages of spermatogenesis.

Comparative gonadotropin pharmacology: Studies comparing HMG to recombinant FSH and recombinant LH preparations have characterised how differences in glycosylation profile, isoform composition, and FSH/LH ratio influence receptor activation kinetics, biological potency, and the pharmacodynamic profile of gonadotropin stimulation in reproductive biology research models.

HPG axis research: Studies using HMG in HPG axis research have characterised the gonadal hormone responses to combined gonadotropin stimulation and the negative feedback mechanisms through which gonadal steroids and peptide hormones regulate pituitary gonadotropin secretion — contributing to understanding of the regulatory biology of the reproductive endocrine axis.

What is the Difference Between HMG and Recombinant FSH?

HMG contains both FSH and LH activity in approximately a 1:1 ratio — making it suitable for research requiring combined gonadotropin stimulation. Recombinant FSH provides pure FSH receptor activation with no LH activity — used when isolated FSH receptor pharmacology is the research objective. The two are complementary tools for studying FSH-only versus combined gonadotropin biology.

What is the Difference Between HMG and HCG?

HMG provides combined FSH and LH activity. HCG (human chorionic gonadotropin) provides LH-like activity only — binding and activating the LH receptor but with a substantially longer half-life than native LH. HCG is used as an LH receptor agonist reference compound, while HMG is used when combined FSH/LH gonadotropin stimulation is required.

What is the Two-Cell Model of Steroidogenesis and How Does HMG Relate to it?

The two-cell model describes how ovarian oestrogen production requires coordinated FSH and LH activity across two cell types — LH driving androgen production in theca cells and FSH driving aromatase-mediated conversion of those androgens to oestrogen in granulosa cells. HMG’s combined FSH/LH activity provides both signals simultaneously — making it the reference tool for studying this coordinated steroidogenesis model in ovarian biology research.

What is the Difference Between HMG and Highly Purified HMG (HP-HMG)?

Standard HMG contains both FSH and LH activity alongside urinary protein impurities from the extraction source. Highly purified HMG (HP-HMG) undergoes additional purification steps to remove urinary proteins while retaining the FSH/LH activity profile. HP-HMG provides a cleaner preparation for research applications where urinary protein contaminants may confound experimental results.

How Does HMG Relate to the HPG Axis in Research?

HMG provides the peripheral gonadotropin stimulus that would normally be produced by pituitary gonadotroph cells in response to hypothalamic GnRH. In HPG axis research, HMG is used to examine the gonadal responses to exogenous gonadotropin stimulation — bypassing the hypothalamic and pituitary components to study the gonadal tier of the axis in isolation.

How Do I Reconstitute HMG for Laboratory Use?

Reconstitute with sterile water or appropriate laboratory buffer by adding the solvent slowly down the vial wall and swirling gently. Prepare at your required concentration, aliquot, and store at -80°C. Standard protein handling protocols apply — avoid repeated freeze-thaw cycles.

How Quickly is HMG Delivered to Europe?
