Progesterone Supplement and Luteal Phase Deficiency in Unifollicular Intrauterine Insemination Cycles

Abstract

Aim: Intrauterine insemination is a widely used technique with advantages of being a simple and less invasive method with a lower cost when compared to other assisted reproductive techniques. In the present prospective randomized controlled study we aim to prove that progesterone supplementation is a beneficial factor in pregnancies achieved with intra uterine insemination and also we want to emphasise that luteal phase deficiency does not always occur in multifollicular cycles but can be seen in unifollicular cycles as well. Material and Method: Patients diagnosed with unexplained infertility between December 2011 and December 2012 were admitted to the study group. 278 IUI cycles with COH using recombinant FSH induction were recorded. Results: The effect of progesterone supplement on achieving pregnancy was statistically significant (p<0.05) with a rate of 33.66% when compared to the non-receiving group that had a rate of 12.22%. Discussion: Progesterone supplementation, either in defective luteal phase or not has a chance of improving pregnancy rates in general and contrary to the notion that luteal phase deficiency mainly occurs in multifollicular cycles, it can be seen in unifollicular patients as well.
