A synthetic GnRH agonist decapeptide that suppresses gonadotropin and sex hormone production for treating prostate cancer, endometriosis, and precocious puberty.
This study compared safety reports for five long‑acting GnRH drugs, including triptorelin, and found that they all can cause serious side effects, especially reproductive and breast problems. Buserelin tends to cause stomach issues, while histrelin is linked to mental‑health problems, and adults face higher risks than kids. The findings help anyone thinking about using these drugs for hormone control to pick the safest option and watch for specific side effects.

The study shows that in premenopausal breast‑cancer patients on the GnRH agonist triptorelin, about one‑fifth don’t get full ovarian suppression as measured by estradiol (E2) levels. Regular E2 testing (monthly) can spot this, and switching to a different GnRH agonist can restore suppression in roughly half the cases. This suggests that hormone‑blocking protocols need routine hormone checks and flexibility in drug choice.

Giving two small shots of the hormone triptorelin (0.2 mg each, 12 hours apart) before freezing and later transferring embryos leads to better pregnancy and birth rates than just one shot, according to a study of Chinese women undergoing IVF.
A 6‑month injectable form of the hormone‑blocking peptide triptorelin safely halted early puberty signs in kids and helped them grow closer to their expected adult height, with no side effects reported.

A study in Chinese women with endometriosis showed that a 3‑month injectable form of the hormone‑blocking peptide triptorelin works just as well as the standard monthly injection, with over 98% of patients reaching the desired low estrogen levels and similar pain relief. This means you can get the same effect with fewer shots, which may be easier to manage.
A small study showed that men with a specific type of infertility (high FSH, no sperm) can sometimes start making sperm again when they take a GnRH agonist (triptorelin) to calm the pituitary, followed by hormone shots (menotropin) to stimulate the testes. In both cases, sperm showed up, hormone levels improved, and after IVF with their partners, the couples had healthy babies. The approach could be an alternative to surgical sperm retrieval, but it’s based on only two patients and needs medical oversight.
In a study of 1,010 kids with early puberty who got the hormone drug triptorelin (or leuprolide), only seven had mild side effects (about 0.7%). None had life‑threatening allergic reactions. The mild issues were things like tiny skin abscesses, hand tremors, a rash, vomiting, or muscle stiffness, and they resolved without serious problems.

Scientists made a tiny patch with silk‑based microneedles that can hold the hormone‑blocking peptide triptorelin and release it slowly through the skin. In rats the patch kept testosterone very low for at least a week, showing it could work as a long‑acting, needle‑free way to suppress sex hormones.

In a small study of 21 young women undergoing egg donation cycles, using a vaginal progesterone spray every 12 hours worked just as well as taking oral dydrogesterone to stop the body from releasing an early LH surge before egg retrieval. Both groups had similar numbers of follicles and mature eggs, and none got ovarian hyperstimulation syndrome after the GnRH‑agonist trigger (triptorelin).

A review of real‑world studies found that the GnRH antagonist degarelix may raise the chance of serious heart problems compared to GnRH agonists like triptorelin, especially in men who already have heart disease. However, the data aren’t perfect and could be influenced by doctors giving the drug to higher‑risk patients.

The study looks at using a GnRH‑agonist drug (triptorelin) to trigger egg release in IVF cycles that involve back‑to‑back stimulations (DuoStim). It finds that this method safely causes the eggs to mature without hurting the next round of stimulation, making it a good alternative to the usual hCG trigger, especially when all embryos are frozen for later use.
In a young male Labrador, using a deslorelin implant for hormonal castration together with a cyproterone acetate injection caused stomach upset, diarrhea, and lasting tiredness because the drugs suppressed the adrenal hormone system. Giving low‑dose prednisolone helped a bit, but the dog only felt normal again after the implant was surgically removed. The adrenal glands later returned to normal function.

In dogs, a slow‑release GnRH agonist (deslorelin) temporarily shrinks the epididymis and stops sperm production, but once the implant is removed the tissue returns to normal within a few weeks as testosterone levels rise again.
The study looked at men with prostate cancer who were given hormone shots (triptorelin, leuprorelin, or goserelin) every 3 or 6 months for two years. Almost all kept using the same drug, only a few switched between 3‑month and 6‑month versions, mainly for convenience. Quality‑of‑life stayed steady, with no change in urinary or bowel issues and a slight boost in sexual activity, and both doctors and patients were very satisfied.

In real‑world reports, the GnRH agonist triptorelin (and similar drugs) shows about a 5% chance of heart‑related side effects, while the antagonist degarelix shows a slightly lower risk. Younger men (<65) have very low heart risk, but serious or even fatal events can still happen, especially with the agonists. This suggests that if you’re using hormone blockers, the type of drug matters for heart health.

The study shows that a single dose of the hormone‑blocking peptide triptorelin triggers a strong LH surge in all women, but the rise in FSH is much weaker in women with PCOS or polycystic ovaries. Higher AMH levels (a marker of ovarian reserve) predict an even smaller FSH response, whether the ovaries are stimulated or not.

A new drug called MVT-602, which mimics the kisspeptin hormone, safely triggers a strong LH surge and ovulation in healthy women, working about as well as the standard drug triptorelin but with a short half‑life. The study shows that a single sub‑cutaneous dose of 3 µg reliably caused ovulation within 3‑4 days, while lower doses were still effective but less consistent.

The study shows that the hormone INSL3, which comes from testicular Leydig cells, drops in the same way as testosterone and LH when the testes are chemically or surgically suppressed, and it rises back when suppression stops. This means INSL3 can be used as another indicator of how the testes are functioning during hormone therapies or testosterone use.

An 88‑year‑old man with advanced prostate cancer was on enzalutamide, denosumab and the peptide drug triptorelin when he developed chest pain. Tests showed a myocardial bridge (a heart artery that runs under heart muscle) but no heart attack. Doctors added ranolazine and a statin, kept the cancer drugs, and his heart stayed stable during follow‑up. This suggests that with careful cardiac monitoring, you can continue androgen‑blocking therapy even in older patients with some heart anomalies.

In a year‑long study of transgender people, estradiol lowered liver fat in trans women, while testosterone raised liver and visceral fat in trans men unless an aromatase blocker (anastrozole) was added. The GnRH agonist triptorelin was used to suppress natural hormones but didn’t directly cause the fat changes.
