However, this impact can be influenced by various factors such as timing of P4 administration and P4 dosage. Moreover, there are different types of P4 administration such as oral and vaginal P4 supplementation, which can alter the impact of P4 on pregnancy rate. This literature article discusses the function of progesterone, the effect of P4 on embryo transfer and the optimal level of serum before embryo transfer. %K Progesterone Function %K Serum Progesterone and Embryo Transfer %K Progesterone Supplementation Route and Administration Timing %K Why Optimal P4 Level Is Vital %U http://www.oalib.com/paper/6713636
