Oxytocin
Contracts the myometrium, the uterine muscle, to drive labor and stop bleeding after birth. Online it's also sold as a love spray.
The Empress · FDA approved
Kisspeptin-10
The active end of kisspeptin, which wakes GnRH neurons, the brain's master switch for sex hormones. Sold to raise testosterone.
Wheel of Fortune · In clinical trials
Cetrorelix
Blocks GnRH receptors in the pituitary, halting the LH surge that would release eggs before IVF retrieval. Nobody leaves early.
FDA approved
Degarelix
Shuts the pituitary's GnRH receptor, the sex-hormone switch, so testosterone falls in days with no first surge. For prostate cancer.
FDA approved
Ganirelix
Daily IVF shots that occupy the pituitary's GnRH receptor without firing it, holding back LH, the hormone that triggers ovulation.
FDA approved
Gonadorelin
Unaltered GnRH, the brain's pulsed signal to the pituitary, sold to keep testes active on testosterone. Nonstop, it shuts them off.
Not FDA approved
Goserelin
A 1 mm implant that floods the pituitary's GnRH receptors until they go deaf, so sex hormones fall. For prostate and breast cancer.
FDA approved
hCG
The placental hormone pregnancy tests detect. It mimics LH right in the ovaries and testes, triggering ovulation or testosterone.
FDA approved
Histrelin
A year-long arm implant releasing a GnRH copy, the brain's puberty signal, nonstop until the pituitary tunes out. Puberty, paused.
FDA approved
Leuprolide
A depot copy of GnRH, the brain's sex-hormone signal: testosterone surges in week one, then the pituitary shuts it off for months.
FDA approved
Lutetium-177 PSMA
Homes in on PSMA, a protein on prostate cancer cells, and irradiates them with lutetium-177, whose rays travel only about 2 mm.
FDA approved
Nafarelin
A nasal-spray GnRH copy: only a few percent reaches blood, yet enough to switch off the pituitary and estrogen. For endometriosis.
FDA approved
Triptorelin
Brief GnRH signals make the pituitary fire; constant ones silence it. A long-acting shot for prostate cancer and early puberty.
FDA approved
