PURPOSE: To determine whether differences in birth outcomes among assisted reproductive technology (ART)-treated, subfertile, and fertile women exist in primiparous women with, singleton, vaginal deliveries. METHODS: Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) data were linked to Massachusetts vital records and hospital discharges for deliveries between July 2004 and December 2010. Primiparous women with in-state vaginal deliveries, adequate prenatal care, and singleton birth at ≥ 20 weeks (n = 117,779) were classified as ART-treated (linked to ART data from SART CORS, n = 3138); subfertile (not ART-treated but with indicators of subfertility, n = 1507); or fertile (neither ART-treated nor subfertile, n = 113,134)...

PURPOSE: Primary ovarian insufficiency (POI) is a clinical condition observed in women younger than 40 years of age, characterized by amenorrhea, hypoestrogenism, high levels of follicle-stimulating hormone (FSH), and infertility. Mutations in some master regulators of the development, maturation, and maintenance of ovarian follicles such as BMP15, FSHR, FOXL2, and GDF9 have been suggested as etiological factors in the development of POI. The aim of this study, the first in the Mexican population, is to evaluate the presence of mutations or polymorphisms in these four candidate genes...

Here we examine recent evidence suggesting that many drugs and diet supplements (DS), experimental AMP-activated protein kinase (AMPK) agonists as well as energy-depleting stress, lead to decreases in anabolism, growth or proliferation, and potency of cultured oocytes, embryos, and stem cells in an AMPK-dependent manner. Surprising data for DS and drugs that have some activity as AMPK agonists in in vitro experiments show possible toxicity. This needs to be balanced against a preponderance of evidence in vivo that these drugs and DS are beneficial for reproduction...

PURPOSE: To evaluate the possibility of correcting metabolic defects in gametes and embryos due to methylene tetra hydrofolate reductase (MTHFR) isoforms C677T and A1298C, by supplementation with 5-methyl THF instead of synthetic folic acid. In these couples, high doses of folic acid lead to UMFA (un-metabolized folic acid) syndrome. METHODS: Thirty couples with fertility problems lasting for at least 4 years, such as recurrent fetal loss, premature ovarian insufficiency, or abnormal sperm parameters, with two thirds of them having failed assisted reproductive technology (ART) attempts were included in this program...

EDITORIAL
Avner Hershlag, Sara L Bristow
The rapid development of gene-editing technologies has led to an exponential rise in both basic and translational research initiatives studying molecular processes and investigating possible clinical applications. Early experiments using genome editing to study human embryo development have contradicted findings in studies on model organisms. Additionally, a series of four experiments over the past 2 years set out to investigate the possibilities of introducing genetic modifications to human embryos, each with varying levels of success...

PURPOSE: Oocyte vitrification is currently used for human fertility preservation. However, vitrification damage is a problem caused by decreasing ooplasmic levels of glutathione (GSH). The GSH donor glutathione ethyl ester (GSH-OEt) can significantly increase the GSH content in oocytes. However, it is difficult to obtain oocyte from woman. To overcome this, we used mouse oocytes to replace human oocytes as a model of study. METHODS: Oocytes from B6D2F1 mice were preincubated for 30 min with 2...

PURPOSE: Human oocytes are arguably one of the most important cell types in humans, yet they are one of the least investigated cells. Because oocytes are limited in number, the use of high-quality oocytes is almost entirely in reproduction. Furthermore, regulatory hurdles for research on gametes and regulations on funding related to research on gametes present significant obstacles to research and the advancement of reproductive treatments. Here we report the outcomes of the largest compensated oocyte donation program for research in the USA to date, and probably worldwide...

PURPOSE: To assess effects on fertilization rate, embryo quality, pregnancy, and live birth rates of vitrification and warming of oocytes that matured in vitro (vIVM) compared to fresh in vitro maturation (fIVM) cycles. METHODS: A retrospective cohort study conducted at a university hospital-affiliated IVF unit. Fifty-six cycles of vIVM cycles and 263 fIVM in women diagnosed with polycystic ovarian syndrome (PCOS) ovaries were included in the analysis. The study group included PCOS patients who failed ovulation induction with intrauterine insemination and were offered IVM cycle followed by oocyte vitrification and warming...

PURPOSE: Cell-free DNA (cfDNA) which is present in the blastocoel cavity of embryos is believed to result from physiological apoptosis during development. This study assessed cfDNA content and caspase-3 protease activity in day-5 IVF blastocysts to determine if there was a correlation with embryo morphology. METHODS: Day-5 IVF blastocysts were scored according to the Gardner and Schoolcraft system (modified to generate a numerical value) and cfDNA was collected following laser-induced blastocoel collapsing prior to cryopreservation in 25 μL of media...

The inability to conceive is an immensely stressful event in a woman's life. Thus, it is no surprise that women with infertility have twice the rates of depressive symptoms as women without infertility. Incidence of depression in the general female population is approximately 20% compared to almost 40% in infertile females. Based on this information, we expect many individuals with infertility to have pre-existing mood disorders requiring ongoing treatment. In addition, we expect a subset of women to develop a mood disorder during infertility treatment due to related stressors...
