Many factors can affect the success rate of IVF including:
Age – Egg quality and quantity, both predictors of IVF success rates, decline with age.
Ovarian Reserve – The quantity of an individual’s eggs, known as ovarian reserve, can impact an IVF cycle. Tests such as antral follicle count (AFC) and anti-Müllerian hormone (AMH) levels can assess ovarian reserve.
Underlying cause of infertility – Certain pre-existing conditions such as endometriosis, PCOS or POI, or endometrial receptivity issues, may affect IVF outcomes.
Sperm health – Sperm health (count, motility, morphology and DNA integrity) directly affect fertilization rates.
Lifestyle – Factors such as smoking, body weight, alcohol use, diet, and stress can all negatively impact IVF success.
Stimulation protocols and lab factors – The experience and expertise of the fertility clinic and medical team can influence success rates.
Embryo quality – The quality of the embryo transferred directly impacts success. Quality is assessed based on factors such as cell division rate, embryo morphology and genetic integrity.
