A first post–embryo transfer serum beta-human chorionic gonadotropin level of 1.0–5.0 mIU/mL may not exclude pregnancy and is associated with poor outcomes compared with a level <1.0 mIU/mL. Serial testing may be warranted.
Twelve year retrospective review of unintended pregnancies after Essure sterilization in the Netherlands
The incidence of pregnancies after sterilization with Essure is low. Most pregnancies were related to nonadherence to placement and follow-up protocols or misinterpretation of confirmation tests, and seem therefore preventable.
Reporting in vitro fertilization cycles to the Society for Assisted Reproductive Technology database: where have all the cycles gone?
Clinics with significantly higher rates of nonreportable in vitro fertilization cycles present higher live birth rates compared with all other clinics in the United States.
Increased incidence of gestational hypertension and preeclampsia after assisted reproductive technology treatment
After assisted reproductive technology (ART), mothers had a 17% increased likelihood of gestational hypertension and preeclampsia compared with non-ART mothers, which was likely associated with the ART mothers’ multiple pregnancies.
Blastocoele expansion degree predicts live birth after single blastocyst transfer for fresh and vitrified warmed single blastocyst transfer cycles
The degree of blastocoele expansion is a better predictor of live birth after both fresh and vitrified/ warmed single blastocyst transfer cycles than inner cell mass and trophectoderm.
A low estradiol level at the time of a first positive pregnancy test after in vitro fertilization is associated with poorer pregnancy outcomes but does not preclude the possibility of a live birth.
Effect of semen quality on human sex ratio in in vitro fertilization and intracytoplasmic sperm injection: an analysis of 27158 singleton infants born after fresh single embryo transfer
Lower sperm motility was associated with significant lower sex ratio in in vitro fertilization whereas intracytoplasmic sperm injection was associated with significant lower sex ratio regardless of sperm quality.
Reflections on “Cesarean scar pregnancy—a systemic review of treatment studies” by Birch Peterson et al.
Reflections on “Reporting in vitro fertilization cycles to Society for Assisted Reproductive Technologies (SART) database: where have all the cycles gone?” by Kulak et al.
This document provides updated coding information for services related to assisted reproductive technology procedures. This document replaces the 2012 ASRM document of the same name.
We discuss the ethical considerations related to human reproductive cloning (somatic cell nuclear transfer). Arguments are presented justifying the conclusion that the process is unethical.
Microsurgical reconstruction for male infertility is a relatively recent development in the history of urology therapy. The results of the first microsurgical vasovasostomy (VV) were published in the late1960s, and this epic achievement has been followed by almost fifty years of microsurgical innovation (1). Despite the well-established success of microsurgery, the role of male reproductive tract reconstruction has been called into question because of the many advances made in assisted reproductive technology (ART).
For the infertile woman with tubal damage, there are only two realistic options for achieving a pregnancy: reconstructive surgery or in vitro fertilization (IVF). Until the 1980s, reconstructive surgery was the only therapeutic option for infertility caused by tubal and peritoneal factors. Traditional techniques yielded poor outcomes, often as a result of extensive postoperative adhesions. This led to the development of gynecologic microsurgery in the early 1970s. In addition to the use of magnification, microsurgery introduced a broad concept of surgery designed to be more precise, to minimize trauma and tissue damage, and to avoid an acute inflammatory reaction in the peritoneal cavity to obtain better results and prevent postoperative adhesions.
Social media, as defined by Wikipedia, the social encyclopedia, is a computer-mediated tool that allows people to create, share, or exchange information, career interests, ideas, and pictures/videos in virtual communities and networks. A Google search for the term yields 1.2 billion hits and you are hard pressed to get through your morning coffee without being asked to give or receive information through one of the many outlets that fall under this umbrella.
Some medical conditions and lifestyle factors can influence implantation in the setting of IVF. Multiple endometrial and circulating factors affecting implantation will be reviewed.
Optimal endometrial preparation for frozen embryo transfer cycles: window of implantation and progesterone support
Improvements in cryopreservation technology resulted in greater availability of frozen embryos for transfers. Optimal endometrial preparation and timing of transfers are essential for improvements in frozen embryo transfer pregnancy rates and outcomes.
Both slowly developing embryos and a variable pace of luteal endometrial progression may conspire to prevent normal birth in spite of a capable embryo
Embryonic implantation requires synchrony between the endometrium and the embryo.
Meticulous ET technique, aided by ultrasound guidance, is essential to optimal outcomes with assisted reproductive technology.
Anatomic and functional anomalies of the uterus, including those occurring as a result of pathologies lying outside the uterus, such as endometriosis and hydrosalpinges, should be elucidated, with appropriate measures taken to optimize assisted reproductive outcome.
Examining the many potential reasons why euploid blastocysts do not always result in viable pregnancies and deliveries: part 2
A viable delivery requires optimal embryo transfer technique, a receptive and synchronized endometrium, a physiologically and anatomically adequate uterus, and absence of local and circulating factors capable of disrupting implantation.
