Optimal lead follicle size for human chorionic gonadotropin trigger in clomiphene citrate and intrauterine insemination cycles: an analysis of 1,676 treatment cycles.

Objective: To identify the optimal lead follicle size for hCG trigger in clomiphene citrate (CC)-intrauterine insemination (IUI) cycles.

Design: Retrospective cohort study.

Setting: University-affiliated center.

Fresh or Frozen Embryo Transfer in In Vitro Fertilization: An Update.

The past decade has witnessed a rapid increase in the number of frozen-thawed embryo transfer (FET) cycles. Several factors have contributed to the increase in FET cycles, including improvement in culture media, vitrification, and an increase in preimplantation genetic testing of embryos. However, the accelerated trend in FET cycles also suggests that FET may be preferred over fresh embryo transfer.

Perinatal Risks Associated with Early Vanishing Twin Syndrome following Transfer of Cleavage- or Blastocyst-Stage Embryos.

. To investigate whether the perinatal risks associated with early vanishing twin (VT) syndrome differ between cleavage- or blastocyst-stage embryo transfers (ET) in fresh in vitro fertilization (IVF) cycles. .

Pretreatment of normal responders in fresh fertilization cycles: A comparison of transdermal estradiol and oral contraceptive pills.

Objective: The aim of this study was to investigate the impact of pretreatment with transdermal estradiol (E) compared to oral contraceptive pills (OCPs) on controlled ovarian stimulation (COS) response in normal responders undergoing fresh fertilization (IVF)-embryo transfer (ET) cycles.

Methods: A retrospective cohort study was performed of normal responders undergoing fresh IVF-ET cycles who received pretreatment with transdermal E versus OCPs prior to fresh IVF-ET. The total days of ovarian stimulation, total dosage of gonadotropins, total number of oocytes, and mature oocytes retrieved were noted.

Early spontaneous multiple fetal pregnancy reduction is associated with adverse perinatal outcomes in in vitro fertilization cycles.

The primary objective of this study is to investigate whether early spontaneous multiple fetal pregnancy reduction, also known as vanishing twin syndrome, is associated with adverse perinatal outcomes in fresh in vitro fertilization cycles. This is a retrospective cohort study of women with live singleton births with and without an early vanishing twin after fresh in vitro fertilization. Characteristics compared included incidence of preterm birth, overall birth weight, overall low birth weight, overall very low birth weight, and term low birth weight.

Comparison of perinatal outcomes following fresh and frozen-thawed blastocyst transfer.

Objective: To investigate the effect of ovarian stimulation on endometrial receptivity by comparing singleton pregnancy and perinatal outcomes following fresh or frozen-thawed blastocyst transfers.

Methods: A retrospective cohort study enrolled patients undergoing fresh or frozen-thawed blastocyst transfers that resulted in live deliveries between January 1, 2010 and September 30, 2013 at a single academic center. Implantation, clinical pregnancy, spontaneous abortion, and live delivery rates were calculated.

Is anti-Müllerian hormone associated with IVF outcomes in young patients with diminished ovarian reserve?

Aim: To investigate whether anti-Müllerian hormone (AMH) is associated with IVF cycle outcomes in young patients with diminished ovarian reserve.

Materials & Methods: Retrospective study of patients <35 years of age undergoing fresh IVF who had at least two 8-cell, day-3 embryos transferred with grades 1, 1.5 or 2.

Surgical Management of Endometrial Polyps in Infertile Women: A Comprehensive Review.

Endometrial polyps are benign localized lesions of the endometrium, which are commonly seen in women of reproductive age. Observational studies have suggested a detrimental effect of endometrial polyps on fertility. The natural course of endometrial polyps remains unclear.
