What Factors Affect the Success of IVF?

Every IVF cycle is different. Success depends on egg quality and quantity, sperm health, embryo development in the laboratory, uterine receptivity, and the underlying fertility diagnosis. Age is one of the most significant variables -- egg quality and quantity decline naturally after 35, which affects both the number of embryos available and their potential for implantation. At Jeevasare Healthcare and KIMS Lakshya, Bengaluru, I use AMH testing and antral follicle count to anticipate ovarian response and guide the stimulation protocol for each individual cycle. Knowing the key variables in advance allows us to design the most appropriate protocol for each couple.
