Effect of a GnRH antagonist on the fate of the dominant ovarian follicle and the emergence of the next follicular wave in alpacas.
(PubMed, Theriogenology)
- "In conclusion, treatment with a single or double dose of 1.5 mg Cetrorelix caused the demise of dominant follicle leading to synchronous emergence of the next follicular wave 5 days (single dose) or 8 days (two doses) later. Results document the potential utility of Cetrorelix in breeding management protocols that enable pre-scheduled, synchronous insemination."

From Ovarian Hyperstimulation Syndrome (OHSS) to Cortical Necrosis: A Rare Renal Catastrophe
(KIDNEY WEEK 2025)
- "Case Description A 26-year-old woman with primary infertility underwent controlled ovarian stimulation using rFSH, hCG, and cetrorelix...Prompt initiation of fluids, albumin, vasopressors, and RRT is critical for managing this condition. With the increasing use of assisted reproduction, vigilant monitoring during ovarian stimulation is vital to prevent such outcomes."

Substituting DDGS with soybean meal in finishing diets: Effects on small intestinal amino acid flow, digestibility, and nitrogen balance.
(PubMed, J Anim Sci)
- "Treatments were: 1) 15.0% DDGS (CON); 2) SBM in replacement of 50% of DDGS (SBM50); 3) SBM in replacement of 75% of DDGS (SBM75), and 4) SBM in replacement of 100% of DDGS (SBM100)...Ultimately, DDGS and SBM deliver similar metabolizable amino acids in beef cattle finishing diets. This allows producers to prioritize cost-effectiveness and regional availability when selecting a protein source."

Phoenixin-14 ameliorates acetic acid-induced ulcerative colitis in rats via antioxidant, anti-inflammatory and anti-apoptotic mechanisms.
(PubMed, Peptides)
- "The control group was treated intraperitoneally with saline, while the colitis groups were treated intraperitoneally with saline or PNX-14 (50 μg/kg/d) or gonadotrophin-releasing hormone (GnRH)-antagonist cetrorelix (CTX; 100µg/kg/d) or CTX and PNX-14 or sulfasalazine as a positive control (100mg/kg/d) instantly and once a day for 3 days following colitis induction. PNX-14, which alleviates macroscopic, histological and biochemical parameters, can be considered as a potential therapeutic agent in ulcerative colitis with its anti-inflammatory, antioxidant and anti-apoptotic actions. Furthermore, despite its effects as an GnRH-antagonist, CTX has also revealed a similar beneficial role as PNX-14 in this ulcerative colitis model."

Intranasal Delivery of Cetrorelix Via Lipid Liquid Crystal Nanoparticles: Characterization and Pharmacokinetic Studies in Rats.
(PubMed, AAPS PharmSciTech)
- "This study introduces, for the first time, a cetrorelix-loaded lipid liquid crystal (LLC) nanoparticle formulation for intranasal nose-to-brain delivery. The LLC system achieved enhanced brain targeting efficiency while reducing systemic exposure compared to conventional subcutaneous injections and simple nasal formulations, representing a promising advancement in GnRH drug delivery strategies."

Investigating dosage effects of ovulation inhibitors on oocyte maturation in assisted reproductive technology: A retrospective study among patients with normal ovarian reserve.
(PubMed, PLoS One)
- "Herein, we investigate the dose-dependent effects of chlormadinone acetate (CMA) and cetrorelix, two distinct ovulation inhibitors, on oocyte maturation in patients with normal ovarian reserve, using univariable and multivariable Poisson regression analyses...Collectively, these findings indicate that within the applied dosages, ovulation inhibitors do not significantly impact oocyte maturation or fertilization rates in patients with normal ovarian reserve. These valuable insights can be applied when designing ART protocols and may guide clinicians in optimizing infertility treatments."
