Postpartum hemorrhage among twin pregnancies - Medically assisted versus spontaneously conceived.

Introduction: In singleton pregnancies, an increased risk of Postpartum hemorrhage (PPH) have been linked with assisted reproductive technology (ART) and abnormal placentation. It is unknown wheather such association exists in twin pregnancies conceived by Medically assisted reproduction (MAR). The aim of the current study was to compare maternal blood loss among twin pregnancies conceived by different types of MAR treatments to spontaneously conceived twins and to identify the cycle characteristics if an association exits.

Perimortem and postmortem sperm acquisition: review of clinical data.

Purpose: To provide the clinicians with the most comprehensive medical information about sperm acquisition peri/postmortem.

Methods: The review was conducted according to the PRISMA statement. MEDLINE and Cochrane databases were searched up to January 2021.

Progesterone and estrogen levels are associated with live birth rates following artificial cycle frozen embryo transfers.

Purpose: Does an association exist between serum progesterone and estradiol levels and live birth rates in artificial cycle frozen embryo transfer (AC-FET)?

Methods: Retrospective cohort study was based on prospectively collected data at a university-affiliated fertility center. Included were all cycles using an artificial endometrial preparation with estradiol hemihydrate (Estrofem, 2 mg/8 h) and vaginal progesterone (Endometrin 100 mg/8 h), autologous oocytes, and cleavage stage embryo transfers. Serum progesterone and estradiol levels were measured 14 days after FET.

Survey of faculty development in four Israeli medical schools: clinical faculty development is inadequate and clinical teaching is undervalued in Israeli faculties of medicine.

Background: Teaching medical students is a central part of being a doctor, and is essential for the training of the next generation of physicians and for maintaining the quality of medicine. Our research reviews the training that physicians in Israel receive as teachers of clinical clerkships, and their thoughts regarding teaching students. The importance of faculty development cannot be overstated, for securing quality medicine and physician empowerment.

Should the modified natural cycle protocol for frozen embryo transfer be modified? A prospective case series proof of concept study.

Objective: Modified natural cycles for frozen embryo transfer utilize an ovulation trigger which assists in embryo transfer scheduling and simplifies cycle monitoring. There have been conflicting results with this protocol and modifications may be sought. We wanted to ascertain whether a modified natural protocol for frozen embryo transfer without triggered ovulation but with luteal progesterone support disconnecting the timing of embryo transfer from the timing of the LH surge can achieve a high pregnancy rate.
