Sexual Health

Glycoprotein hormone the placenta produces naturally during pregnancy; binding at LH receptors stimulates biosynthesis of testosterone and estrogen. FDA approval covers cryptorchidism, hypogonadotropic hypogonadism, and ovulation induction.

Master regulator of the reproductive system: it stimulates the GnRH neurons on which puberty, fertility, and reproductive function depend.

Synthetic form of GnRH (gonadotropin-releasing hormone), which occurs naturally. It acts on the pituitary gland, which then releases luteinizing hormone (LH) and follicle-stimulating hormone (FSH); those two go on to regulate ovulation in women and testosterone production in men. FDA approval covers fertility treatment and diagnostic testing. GnRH is secreted in pulses, and that pattern is critical to proper reproductive function.

Synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH) whose activity spans melanocortin receptors throughout the body. Melanin production for tanning follows MC1R activation, while the MC4R effect falls on sexual arousal and appetite control.

Khavinson bioregulator tetrapeptide (KEDP) whose primary repair effects fall on prostate tissue. Professor Vladimir Khavinson developed it at the St. Petersburg Institute of Bioregulation and Gerontology; in cells from elderly individuals it alters chromatin structure, promoting deheterochromatinization and potentially reactivating genes repressed during aging. Rat models show prostate inflammation reduced, swelling decreased, and the pathological remodeling associated with prostatitis slowed.

Melanocortin receptor agonist with FDA approval for hypoactive sexual desire disorder (HSDD) in premenopausal women. Its action is central, in the nervous system, triggering sexual arousal pathways that do not depend on the vascular mechanisms behind traditional ED medications.

Khavinson bioregulator tetrapeptide (KEDG), isolated originally from testicular tissue extracts. Professor Vladimir Khavinson developed it at the St. Petersburg Institute of Bioregulation and Gerontology; testosterone biosynthesis is promoted through stimulation of Leydig cell activity and better cellular metabolism in testicular tissue. Research shows normal communication restored within the hypothalamic-pituitary-gonadal (HPG) axis, which governs testosterone production and spermatogenesis.

Hormonally active medication that carries luteinizing hormone (LH) alongside follicle-stimulating hormone (FSH), the two at a 1:1 ratio, extracted from postmenopausal women's urine. Fertility treatment is the FDA-approved use: in women it drives development of ovarian follicles, in men spermatogenesis. Some settings have largely moved to recombinant gonadotropins, but for assisted reproduction and ovulation induction HMG remains effective and cost-efficient.
