The review looks at three hormone treatments for painful endometriosis—GnRH analogues (like gonadorelin), dienogest, and gestrinone. All work, but each has its own side‑effects: GnRH drugs drop estrogen and can hurt bone health unless you add back some hormones; dienogest keeps bone density but can cause irregular bleeding and mood changes; gestrinone is strong and easy on heart and bones but has androgenic effects that many find off‑putting. Choosing the right one depends on what side‑effects you can tolerate.

The study shows that turning off ovarian hormones with a GnRH agonist (leuprolide) stops the mood and physical swings of premenstrual dysphoric disorder (PMDD). When estrogen or progesterone is added back, the symptoms return, especially irritability and mood swings with progesterone. Healthy women don’t develop these symptoms when the same hormones are added back.
A 26‑year‑old woman with PCOS and high basal luteinizing hormone (LH) kept failing to get pregnant with standard IVF hormone protocols that used GnRH agonists or antagonists. When doctors switched to a different approach—using a progestin‑primed ovarian stimulation (PPOS) protocol together with the aromatase inhibitor letrozole and skipping any LH‑lowering pretreatment—the cycle worked and she had a healthy baby. This shows that high basal LH isn’t always a deal‑breaker for IVF, and alternative hormone regimens can rescue a failed cycle.
The study looked at men with Kallmann syndrome and found that their sperm DNA has many extra chemical tags (methyl groups) compared to healthy men. Some of these changes are linked to genes that control brain development, hormone release, and sperm production. After treatment with GnRH or gonadotropins, the DNA still shows these changes, and they are tied to poorer semen quality.
A study of transgender women who took oral estradiol and a GnRH‑agonist (similar to gonadorelin) for about a year and a half showed that the hormone mix kept estrogen and testosterone in the desired range, but it did raise triglyceride levels a bit and lowered red‑blood‑cell counts, though not enough to cause serious problems. Other health markers like cholesterol, blood sugar, and liver enzymes stayed stable.
A large review of 36 Chinese trials (3,577 women) found that taking the herbal Kuntai capsule together with GnRH‑agonist drugs (like gonadorelin) cuts menopausal‑type side effects—hot flashes, trouble sleeping and vaginal dryness—by about half and improves overall symptom scores.

A study in Vietnam found that the hormone pill dienogest is cheaper and gives better quality‑of‑life results than the injectable GnRH‑agonist drugs (like triptorelin, leuprorelin, and goserelin) for treating painful periods caused by endometriosis.

Both dienogest and GnRH agonists (like gonadorelin) work about the same for pain relief and preventing endometriosis lesions after surgery, but they have different side‑effects: dienogest often causes more vaginal bleeding, while GnRH agonists tend to cause hot flushes.

A huge study of US veterans with prostate cancer found that drugs that shut down testosterone production (like leuprolide, goserelin, or triptorelin) raise the chances of heart problems, bone fractures, and osteoporosis for everyone, no matter their race. Black men had a slightly smaller jump in heart risk but a bigger jump in osteoporosis risk compared to White men, but the differences were modest.

In a fish study, giving the brain DHA, EPA, or linoleic acid changed the activity of a fatty‑acid sensor (CD36) and a hormone‑regulating protein (PPARα). This, in turn, altered the levels of the fish's own GnRH genes, which control reproduction. Blocking the sensor or the PPARα pathway reduced these effects, showing the fatty acids act through that route.
A big review looked at kids with early puberty and compared using just a GnRH drug (like gonadorelin) versus adding other hormones such as growth hormone, stanozolol, oxandrolone, or estrogen. Adding growth hormone gave kids a few extra centimeters of predicted adult height and faster growth, but the studies were quite mixed and not all the data were solid. Other drugs showed some promise, but there isn’t enough evidence yet. The benefits were bigger when treatment lasted longer or used higher growth‑hormone doses.

The review explains that women who stop having periods because of stress, intense exercise, or not eating enough (called functional hypothalamic amenorrhea) have low estrogen, high cortisol, and thyroid changes that can damage blood vessels and raise long‑term heart disease risk. Stress itself—not just low estrogen—is a big driver of these problems.

Researchers used machine‑learning to scan large data sets and found that compounds in green tea (epicatechin‑3‑gallate) and almonds might help with PCOS by reducing inflammation and androgen levels. They also confirmed that drugs that affect the gonadotropin‑releasing hormone (GnRH) receptor, like gonadorelin, are linked to PCOS pathways, which matches what we already know.

The study looked at whether the type of hormone used to stimulate egg production (either progesterone‑based or traditional GnRH drugs) changes the chance that embryos have the right number of chromosomes. Across different age groups, the type of drug didn’t matter – age was the only thing that affected chromosome quality.

Adding a gonadotropin‑releasing hormone agonist (GnRHa) to the usual hormone support after IVF embryo transfer in antagonist cycles boosted pregnancy and live‑birth rates compared with standard support alone.

GnRH drugs, which are used for things like fertility problems and some cancers, can mess up your metabolism and heart health. They can make you more insulin‑resistant, raise bad cholesterol, and cause extra belly fat that fuels inflammation, all of which raise the chance of diabetes and heart disease. The biggest warning is for people on these drugs for a long time, especially adults, while we still don’t know much about the effects on kids.
Hormone therapies like combined oral contraceptives, progestins, and GnRH agonists (the same class as gonadorelin) can shrink the scar‑like tissue (fibrosis) in deep infiltrating endometriosis, but they don’t change the fibrous tissue in ovarian endometrioma.
Recent long‑term studies show that using GnRH agonists (like gonadorelin) to pause puberty, followed by gender‑affirming hormone therapy, helps transgender youth feel better mentally and reduces gender‑related distress. The benefits are tied to comprehensive, supportive care rather than the drug alone.
The brain has special cells called KNDy neurons that release three chemicals—kisspeptin, neurokinin B, and dynorphin—to control the timing and strength of GnRH (gonadorelin) pulses, which drive reproductive hormones. Hormones like estrogen, progesterone, and testosterone can also feed back onto these neurons, affecting puberty, menstrual cycles, and fertility issues.
In a pig study, vaccinating against the hormone FSH made the animals eat more efficiently and store less fat, while also changing some meat quality traits. The effect was stronger than a similar vaccine against GnRH. However, the work was done in castrated male pigs, not people, so the findings are only a hint that lowering FSH might affect body fat.
