Abstract According to (WHO) one in every four couples had been found to be affected by infertility in developing countries, with estimated number of more than 186 million ever-married women of reproductive age were maintaining a ”child wish”. Infertility means not being able to conceive after one year of regular unprotected sex, or six months if a woman is 35 years old or older.It constitutes a major social and psychological burden amongst couples, and the prevalence is increasing.The primary goal of assisted reproductive technology (ART) is the birth of a healthy child. This outcome depends on a multitude of non-mutual independent factors, including female age and the effect of ovarian stimulation (OS).The number of oocytes retrieved after OS represents a critical cornerstone of ART since it is an independent predictor of the likelihood of pregnancy.Although the ideal number of oocytes collected after ovum pickup has been a matter of debate in recent years, it seems reasonable to define a typical ovarian response as the retrieval of 10{u2013}15 oocytes after conventional OS.However, a significant proportion of patients who undergo OS are describes according to their response and outcome as poor responders creating an important challenge to the ART |
