Gonadorelin

The model identified 2991 new DDIs involving 192 drugs used in female reproductive conditions and other unrelated treatments.; Most new DDIs involved estradiol, acetaminophen, bupivacaine, risperidone, and follitropin, with follitropin having the highest discovery rate at 42%.; Predicted 12 DDIs between oral contraceptives and HIV drugs that could compromise efficacy.; Among new DDIs, 23 were expected to improve therapies and 11 to cause harmful effects.

Bioanalytical methods have evolved toward simpler, on-site techniques with reduced time and costs.; Affinity reagent production has advanced from natural receptors to biomimetic, animal-free options like aptamers and MIPs.; Peptide hormone analysis remains challenging in biomedical, pharmaceutical, and anti-doping contexts.; Gonadorelin is highlighted as a neuropeptide misused in doping, driving interest in its detection.

A detection limit of 277 pmol L-1 for gonadorelin was achieved.; Reproducibility was good with average CV% of 4.07% in standard solutions and 5.24% in urine samples.; The assay showed adequate selectivity against non-specific control peptides.; Results were successfully validated by mass spectrometry, the reference anti-doping platform.

GnRH at AI did not improve ovulation rate, plasma progesterone 7 days post-AI, or pregnancy per AI in cows detected by traditional estrus detection or AAM.; No treatment effects were observed for pregnancy at P1 (32-45 days) or P2 (60-115 days) in either experiment.; High-activity cows in the AAM system had greater pregnancy per AI and lower pregnancy loss compared to low-activity cows, with no interaction with GnRH treatment.; The study does not support routine use of GnRH at estrus detection to enhance reproductive outcomes.

Both GnRH and NGnRH increased corpora lutea number and twinning rate compared to control.; GnRH treatment increased serum estradiol and progesterone concentrations more than NGnRH and control.; NGnRH achieved similar fertility and prolificacy to GnRH at a quarter of the dose.; Both treatments reduced estrus duration and pregnancy losses compared to control.

Dienogest was compared to placebo, no treatment, gonadorelin analogues, combined oral contraceptives, and other progestogens.; The review included five studies and used GRADE to assess evidence quality.; Ectopic endometrial tissue occurs in 2-6% of reproductive-age women and up to 60% of those with dysmenorrhoea.; Symptoms may not correlate with laparoscopic findings.

Menorrhagia limits normal activities and causes anaemia in two-thirds of women with objective blood loss ≥80 mL per cycle.; Prostaglandin disorders may be linked to idiopathic menorrhagia and heavy bleeding from fibroids, adenomyosis, or IUDs.; Fibroids found in 10% of women with menorrhagia overall, 40% with severe menorrhagia; half of hysterectomies for menorrhagia reveal a normal uterus.; Review included 39 systematic reviews, RCTs, or observational studies with GRADE evaluation for interventions.

Cyclical breast pain resolves spontaneously in 20-30% of women but recurs in 60%.; Non-cyclical pain responds poorly to treatment but resolves spontaneously in half of women.; The review assessed 18 interventions including antibiotics, NSAIDs, and hormonal treatments.

What is Gonadorelin?

**Mechanism of Action** Gonadorelin is a synthetic decapeptide identical to endogenous gonadotropin-releasing hormone (GnRH). It binds to GnRH receptors on anterior pituitary gonadotroph cells, stimulating the synthesis and pulsatile release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This actio

How does Gonadorelin work?

Synthetic GnRH decapeptide that stimulates pituitary LH and FSH release; used diagnostically and to support gonadal function.
