About this compound
Human chorionic gonadotropin (hCG) is a placental glycoprotein hormone built as a heterodimer of an alpha and a beta subunit. It signals through the LH/CG receptor — the same receptor the body's own luteinizing hormone acts on — which makes hCG one of the most valued reference gonadotropins in reproductive-endocrinology research.
By engaging the LH/CG receptor directly, hCG drives the steroidogenic machinery of the gonads — supporting the signaling cascades behind testosterone and estrogen production and giving researchers a reliable, well-characterized tool for probing the hypothalamic-pituitary-gonadal axis.
Supplied lyophilized and dosed in international units (IU), this hCG is prized for its potency, stability, and consistency across Leydig-cell, granulosa-cell, and broader gonadotropin-signaling research models. For laboratory and research use only.
Research overview
LH/CG receptor activation
hCG binds and activates the LH/CG receptor, mirroring the action of luteinizing hormone with a longer, more sustained signal. This makes it a powerful research tool for studying receptor-level gonadotropin signaling and the downstream pathways that govern gonadal function. Its well-defined mechanism is exactly why it serves as a benchmark gonadotropin across reproductive-endocrinology studies.
Steroidogenesis support
Acting through the LH/CG receptor, hCG stimulates the steroidogenic pathways that produce sex steroids in gonadal tissue. In research models it supports robust testosterone and estrogen synthesis, helping investigators map how gonadotropin signaling translates into hormone output. This positions hCG as a go-to reference for steroidogenesis and endocrine-pathway work.
Leydig-cell signaling
In the male gonad, hCG engages Leydig cells to drive androgen-producing pathways, making it a cornerstone of testicular-function research. Studies lean on hCG to explore how LH/CG-receptor stimulation translates into Leydig-cell activity and steroid output. Its reliability and potency make it an enduring standard in this area of reproductive science.
Granulosa-cell & ovarian research
On the female side, hCG signals to granulosa cells, supporting research into follicular development, luteinization, and ovarian steroidogenesis. This makes it a valuable probe for the ovarian arm of gonadotropin signaling and the broader reproductive cycle. Researchers value its consistent, LH-like activity for modeling these processes.
HPG-axis & fertility modeling
Because it acts at the gonadal end of the hypothalamic-pituitary-gonadal axis, hCG is widely used to study reproductive-endocrine feedback and fertility-related signaling. It gives researchers a clean way to stimulate the gonads directly and observe axis-wide responses. This makes it a foundational compound in reproductive-endocrinology and fertility research models.
Stability & research consistency
Supplied lyophilized and dosed in international units (IU), this hCG offers excellent stability and reconstitution behavior for laboratory work. Its consistent, well-characterized activity supports reproducible results across steroidogenesis, Leydig-cell, and granulosa-cell studies. That reliability is what makes it a dependable reference gonadotropin for serious research.
