A synthetic GnRH agonist decapeptide that suppresses gonadotropin and sex hormone production for treating prostate cancer, endometriosis, and precocious puberty.
A young girl with a rare chromosome 15 ring disorder and very short stature was given a hormone called triptorelin (a GnRH analogue) together with growth hormone for six months. She grew about 3.8 cm, and her yearly growth rate went up, showing that this combo can help height in this specific genetic condition. The authors also reviewed other cases and found growth hormone generally helps these patients.

The study compared two IVF stimulation methods for women over 35 with low ovarian reserve. Using a progestin‑based protocol (PPOS) required more hormone medication and longer treatment, but it produced slightly more eggs and better‑quality embryos and reduced early hormone spikes. However, pregnancy and live‑birth rates were about the same as the milder protocol.

In a study on male freshwater stingrays, giving them a GnRH vaccine or deslorelin (a GnRH‑like peptide) implants didn’t stop them from making sperm or behaving aggressively. The vaccine did nothing to testosterone levels, while the implants actually pushed testosterone way up for over a year, which could be harmful. So, at the doses used, these methods didn’t work as a chemical birth‑control and might even cause unwanted hormone spikes.

Adding a small dose of the peptide triptorelin (a GnRH‑agonist) to the usual hCG trigger didn’t change overall egg numbers, but in breast or endometrial cancer patients who were also taking letrozole, it gave them more mature eggs than hCG alone. For most people the extra step isn’t needed, but it could be useful in specific fertility‑preservation cases.
Researchers found a temporary form of early puberty in girls that often goes away on its own within a year, called transient central precocious puberty (T‑CPP). It seems linked to higher use of homeopathic medicines and possible pesticide exposure, and unlike classic cases, it may not need drug treatment like triptorelin.
For pre‑menopausal women with estrogen‑positive early breast cancer who are already suppressing their ovaries (using drugs like triptorelin), swapping tamoxifen for an aromatase inhibitor cuts the chance of the cancer coming back, especially in the first four years, but it doesn’t change overall death rates and may raise the risk of bone fractures.
The study shows that a GnRH‑agonist (deslorelin) quickly shuts down testosterone production in male dogs, then testosterone comes back after a few weeks. During this shutdown, the hormone AMH shoots up while INSL3 falls, reflecting changes in the cells that support sperm and hormone production. These hormone shifts suggest AMH and INSL3 could be useful markers to track how the testes respond to GnRH‑agonist use.
In a 6‑year‑old girl with McCune‑Albright syndrome, raising the dose of the hormone drug triptorelin (used for early puberty) seemed to worsen swelling of the optic nerve, causing vision problems. When the drug was stopped, her eye health got better. This suggests that triptorelin can worsen optic nerve pressure in people who already have skull bone abnormalities, so they need careful eye monitoring.

This review shows that all the GnRH‑agonist drugs, including triptorelin, drop testosterone to very low levels (≤50 ng/dL in a month, ≤20 ng/dL in three months) and have similar side‑effects, but goserelin may keep testosterone a bit lower and is the easiest to give. Survival numbers differ a little between drugs, but overall they work about the same for prostate cancer treatment.

Scientists used computer modeling to see how well existing drugs stick to a protein called STEAP2, which is linked to prostate cancer. They found that the peptide drug triptorelin binds very tightly to this protein, even tighter than another similar drug, leuprolide. This suggests that part of how these drugs work in prostate cancer might involve directly interacting with STEAP2.

In a small study of six female rhesus monkeys, a single 4.7 mg implant of the GnRH‑agonist deslorelin quickly lowered estrogen and progesterone levels and kept them low for up to six months in most animals, though some monkeys started cycling again after about three to four months. One monkey kept bleeding even though progesterone stayed low.
The study shows that measuring follicle‑stimulating hormone (FSH) in 12‑hour urine samples can reliably tell if a puberty‑blocking drug (triptorelin) is working in girls with early puberty, offering a non‑invasive alternative to blood tests.

The study shows that measuring hormone levels just 60 minutes after a single dose of the drug triptorelin can accurately tell if a young girl has early puberty, cutting down the number of blood tests needed.
The study shows that measuring luteinizing hormone (LH) 20, 40, or 60 minutes after a triptorelin injection can accurately tell if the hormonal axis that controls puberty is active in overweight or obese girls, using very high accuracy numbers.
Researchers found that measuring luteinizing hormone in urine after a triptorelin test can accurately tell if a young girl has central precocious puberty, offering a non‑blood alternative for diagnosis.

The study tested giving a hormone drug called triptorelin to mother pigs before a single timed insemination. It didn’t change how many got pregnant or gave birth, but it made more sows have slightly shorter pregnancies and longer nursing periods, and it shifted piglet weights toward heavier babies. For people interested in using peptides for human health, the findings are mostly about pig farming and don’t give clear, actionable advice for humans.
A review of three studies found that the hormone drug triptorelin can lower urinary trouble scores and boost quality of life in men with prostate cancer over about a year, but the evidence is limited and the studies varied a lot.

The study shows that tiny gold particles linked to the peptide triptorelin can make breast cancer cells more vulnerable to radiation, killing more cells than radiation alone. The best dose of these particles was 20 µg/ml, and they boosted radiation effects by about 1.7‑2.3 times depending on the radiation level, also increasing cell death through apoptosis.

A long‑term study in premenopausal women with early hormone‑positive breast cancer found that adding the hormone‑blocking drug letrozole (with or without the bone drug zoledronic acid) to triptorelin lowered the chance of cancer coming back compared to the standard drug tamoxifen, but it didn’t change overall survival.
Giving the GnRH drug triptorelin to sheep 48 hours after stopping a progesterone treatment lowered their pregnancy success and changed blood chemicals linked to uterine tissue and inflammation, suggesting it harms embryo implantation.
