چکیده
Recent findings In random-start protocols, the number of total and mature oocytes retrieved, oocyte maturity rate, mature oocyte yield and fertilization rates are similar to those in conventional (early follicular phase start) protocols. Starting ovarian stimulation in the late follicular or luteal phase did not show any superiority against the other. The presence of corpus luteum or luteal phase progesterone levels did not adversely affect synchronized follicular development, number of mature oocytes retrieved, and/or fertilization rates.

I-31: New Approaches for Luteal Phase Support in ART Cycles
Background During a normal menstrual cycle, progesterone prepares the endometrium for pregnancy by stimulating proliferation in response to human chorionic Gnadotropin produced by the corpus luteum. Many questions were raised about the role of follicular fluid aspiration on the granuloma cells at the time of oocyte retrieving during the ART cycles. Authors believes that oocyte retrieval might d...

Human chorionic gonadotropin (hCG) has been used as a surrogate for the mid-cycle LH surge for several decades. Due to structural and biological similarities with LH, hCG binds to and activates the same receptor - the LH/hCG receptor. However, despite the fact that hCG effectively secures final oocyte maturation and ovulation, its use as a surrogate for LH has got several drawbacks - first and ...

OBJECTIVE To assess whether an early GnRH antagonist start leads to better follicular synchronization and an improved clinical pregnancy rate (CPR). METHODS A retrospective cohort study. A total of 218 infertile women who underwent IVF between January 2011 and February 2013. The initial cohort (Cohort I) that underwent IVF between January 2011 and March 2012 included a total of 68 attempted I...
متن کاملP-81: Discontinuation of rLH Two Days before HCG may Increase the Number of Oocytes Retrieved in IVF
Background: Administration of recombinant luteinizing hormone (rLH) in controlled ovarian hyperstimulation may benefit a subpopulation of patients. However, late follicular phase administration of high doses of rLH may also reduce the size of the follicular cohort and promote monofollicular development. Materials and Methods: To determine if rLH in late follicular development had a negative imp...
