Summary

This trial looks at whether using a "dual trigger" can improve IVF outcomes compared to GnRH agonist (GnRH-a) alone in patients at high risk of OHSS.

Who is the study for?
This trial is for women aged 18-40 undergoing IVF with a risk of Ovarian Hyperstimulation Syndrome (OHSS). They must have at least 13 follicles or high estradiol levels on the day of trigger. Women who've had poor outcomes with dual triggers, low ovarian reserve, are preserving fertility due to cancer, have recurrent implantation failure, or certain medical conditions can't participate.Check my eligibility
What is being tested?
The study tests if a 'dual trigger' (Pregnyl and saline) improves IVF outcomes compared to just GnRH agonist in patients at high OHSS risk. It focuses on oocyte quality and embryo potential by looking only at freeze-all cycles followed by frozen embryo transfers.See study design
What are the potential side effects?
Possible side effects from Pregnyl may include reactions at the injection site, headache, restlessness, depression, fatigue, swelling from fluid retention and rarely hyperstimulation of the ovaries.

Other Research
The most common treatments for Ovarian Hyperstimulation Syndrome (OHSS) include the use of GnRH agonists, hCG, and dopamine agonists. GnRH agonists help by reducing the risk of OHSS through a shorter half-life and less luteal phase support compared to hCG. hCG is used to trigger ovulation but can increase the risk of OHSS due to its longer half-life. Dopamine agonists, such as cabergoline, reduce vascular permeability and thus the severity of OHSS. The 'Dual Trigger' approach, which combines LH and FSH, aims to improve oocyte maturation and embryo quality while potentially reducing the risk of OHSS by optimizing the hormonal environment. This matters for OHSS patients as it can enhance treatment outcomes and minimize complications associated with excessive ovarian stimulation.
Combined gonadotropin releasing hormone agonist/human menopausal gonadotropin therapy (GnRH-a/hMG) in normal, high, and poor responders to hMG.
