One of the most common questions women ask when embarking on the in vitro fertilization (IVF) journey after the age of 35 is: “What is my IVF success rate?” This is a very practical and important question. Indeed, age is one of the most significant factors affecting IVF success rate.
According to the authoritative data from the Society for Assisted Reproductive Technology, we can clearly see how age affects IVF success rate in terms of live birth rate:
By age 35-37, the mean live-birth rate per embryo transfer cycle was about 20.8%.
By age 38-40, this figure falls further to about 12.6%.
These data reflect general biologic trends. But there are many women over the age of 35 who, with the right medical and lifestyle strategies, can significantly improve these odds.
Why Age Hits IVF Success Rate So Hard
After 35, two physiological changes begin to manifest:
- Fewer eggs left (lower ovarian reserve)
- Higher chance of chromosomal abnormalities in the eggs that remain
That means fewer healthy embryos and a higher miscarriage risk. Our goal is to obtain the healthiest possible embryos and give them the best possible home to implant.
Proven Ways Women Over 35 Are Improving IVF Success Rate
- PGT-A (Genetic Screening)
Screening embryos for chromosomes before transfer can push live birth rates to 30–40% per transfer and slashes miscarriage risk. - Individualized Ovulation Induction Protocol
Mini or mild IVF often yields fewer but higher-quality eggs—perfect when quality beats quantity. - Cumulative Cycles and Embryo Freezing
Freeze embryos from multiple cycles, then transfer the best one(s). - Change Lifestyle
Balanced nutrition, regular movement, stress management, and a healthy BMI all improve egg quality and uterine receptivity. - Scientific Nutrient Support
Relevant research shows certain nutrients can support the ovarian environment. For example, the patented Reco18 compound (extracted from soy, clove, sophora flower buds and other natural plants) has been shown in clinical studies to improve cellular energy metabolism and antioxidant defense in ovarian cells. A study published in Frontiers in Endocrinology found it supported better oocyte quality and embryo development potential.
Products like Juvenex Reco18 combine Reco18 with folate, zinc, and other nutrients to offer comprehensive preconception support from the cellular level up.
IVF after 35 is harder—but far from impossible.
