ORAL CONTRACEPTIVE PILLS VERSUS ESTRADIOL VALERATE PRETREATMENT IN GONADOTROPHIN-RELEASING HORMONE ANTAGONIST PROTOCOL

Estradiol Valerate Pretreatment in Short Protocol GnRH-Agonist Cycles versus Combined Pretreatment with Oral Contraceptive Pills in Long Protocol GnRH-Agonist Cycles: A Randomised Controlled Trial

The strategy of in vitro fertilization (IVF) procedures relies on the increasing pregnancy rate and decreasing the risk of premature ovulation and ovarian hyperstimulation syndrome. They are also designed to avoid weekend oocyte retrievals. Combined oral contraceptive (OC) pills are among the medicines used to accomplish these objectives. Alternatively, estradiol can be used instead of OC to ob...

Estradiol valerate pretreatment in GnRH-antagonist cycles.

We read with great interest the Commentary of Griesinger and Kolibianakis (2012) about scheduling oocyte retrieval in GnRH antagonist cycles. Recently, the results of a randomized trial by our group were published, reporting a significant decrease in oocyte retrieval during weekend days following administration of estradiol valerate in the luteal phase of the cycle prior to the stimulated cycle...

Cycle scheduling for in vitro fertilization with oral contraceptive pills versus oral estradiol valerate: a randomized, controlled trial

BACKGROUND Both oral contraceptive pills (OCPs) and estradiol (E2) valerate have been used to schedule gonadotropin-releasing hormone (GnRH) antagonist in vitro fertilization (IVF) cycles and, consequently, laboratory activities. However, there are no studies comparing treatment outcomes directly between these two pretreatment methods. This randomized controlled trial was aimed at finding diffe...
