What is Lutropin alfa?
Recombinant LH analog used to drive Leydig cell testosterone production in the testes. It is mainly studied in reproductive endocrinology and male infertility settings where LH activity is insufficient.
Key Benefits & Mechanisms
stimulates Leydig cells
raises endogenous testosterone
supports testicular steroidogenesis
pairs with FSH for fertility
Research Summary
Lutropin alfa has been evaluated in fertility protocols to restore LH signaling and endogenous testosterone production. It is a direct research/clinical analogue for men with low gonadotropin drive.

Bremelanotide
Bremelanotide (PT-141), cyclic melanocortin receptor agonist
Bremelanotide is a melanocortin receptor agonist best known for on-demand treatment of female hypoactive sexual desire disorder. In research settings it has also been explored for libido and erectile response via central melanocortin pathways.
Sexual HealthKisspeptin-54
Kisspeptin-54 (metastin), 54-amino-acid KISS1 peptide fragment
Kisspeptin-54 is a real human peptide that activates the reproductive axis by stimulating GnRH release and downstream sex-hormone signaling. While it is not a direct erectile drug, it has meaningful literature around sexual behavior, arousal, and fertility-axis modulation.
Sexual HealthKisspeptin-52
Kisspeptin-52 (KISS1-derived peptide fragment)
An endogenous KISS1-derived neuropeptide fragment that activates KISS1R and drives GnRH release upstream of LH and FSH secretion. It is studied as a translational tool for fertility and reproductive-axis physiology.

Buserelin acetate
A synthetic GnRH agonist that initially stimulates then down-regulates pituitary GnRH receptors after repeated exposure. It is used in reproductive medicine to control gonadotropin output and synchronize cycles.
