The Science of Egg Quality and Age
Ovarian reserve, the quantity and quality of your eggs, declines with age. The most significant decline in egg quality begins around age 35 and accelerates after 37. Egg freezing (oocyte cryopreservation) captures eggs at their current age, which is why women who freeze in their late 20s or early 30s have better outcomes than those who freeze in their late 30s.
Egg Freezing: Realistic Success Rates
Live birth rates from frozen eggs depend heavily on age at freezing. For women under 35, approximately 40–50% of frozen egg cycles result in a live birth (per cycle). This drops to 20–30% for women 35–37, and significantly lower after 40. Most clinics recommend freezing 15–20 mature eggs to achieve a reasonable chance of success, which may require 2–3 stimulation cycles.
IVF: When and Why
IVF is appropriate when natural conception isn't possible due to blocked tubes, severe endometriosis, male factor infertility, or unexplained infertility after 12+ months of trying (or 6 months for women over 35). The process involves ovarian stimulation, egg retrieval, fertilisation in the lab, and embryo transfer. Success rates vary significantly by clinic and age, always ask for age-specific success rates from your clinic's own data.
Your Choices Are Valid
Whether you're choosing to conceive now, preserve fertility for later, or use donor eggs or embryos, your reproductive choices are valid and personal. The most important thing is having accurate information to make them. Seek a reproductive endocrinologist for a proper assessment of your current fertility status before making decisions based on generic timelines.
