Dual Trigger Does Not Improve Egg Maturity in Egg Freezing – Fertility Plus

“More Trigger Shots = More Mature Eggs for Egg Freezing? This Major Trial Says ‘Not Necessarily’ – Game-Changing News for Women Freezing Eggs!
When you freeze your eggs, the final ‘trigger’ injection is what helps your eggs reach full maturity before they’re collected. Many clinics use a ‘dual trigger’ – combining two medications – thinking it will give you more usable mature eggs. But does it actually work better?
A new randomized controlled trial put this to the test in 109 women under 40 with good (but not extremely high) ovarian reserve who were doing elective/social egg freezing. Everyone followed the same stimulation protocol. At the end, half received the dual trigger and half received just the GnRH agonist trigger.
The results were clear and reassuring: both groups got almost exactly the same number of eggs – around 9–10 total eggs and about 7–8 mature (MII) eggs per cycle. There was no meaningful difference between the two approaches. Hormone levels the next day were similar, and importantly, no one in either group developed ovarian hyperstimulation syndrome (OHSS).
For women in their 30s planning social egg freezing with moderate ovarian reserve, this means adding extra medication at trigger time didn’t deliver more mature eggs. A simpler single-drug trigger (GnRH agonist alone) worked just as well in this setting.
