This review is a response to the Fellows Forum on testing 2% oxygen for best culture of human blastocysts (J Ass Reprod Gen 34:303-8, 1; J Ass Reprod Gen 34:309-14, 2) prior to embryo transfer. It is a general analysis in support of the position that an understanding of stem cell physiology and responses to oxygen are necessary for optimization of blastocyst culture in IVF and to enhance reproductive success in fertile women.

PURPOSES: At the moment of sex reassignment surgery (SRS), the ovarian tissue is sometimes cryopreserved as fertility preservation option for female-to-male trans men, also called trans men. During this preparation, cumulus-oocyte-complexes (COCs) can be found and in vitro matured. It is not known if these oocytes are developmentally competent. In order to use these oocytes for fertility preservation and subsequent fertilization, a normal spindle structure before and after vitrification is necessary...

Members of the transforming growth factor-beta (TGF-beta) superfamily are key regulators of various physiological processes. Anti-Müllerian hormone (AMH) which is also commonly known as Müllerian-inhibiting substance (MIS) is a member of the TGF-beta superfamily and an important regulator of reproductive organ differentiation and ovarian follicular development. While AMH has been used for diagnostic purposes as a biomarker for over 15 years, new potential therapeutic applications of recombinant human AMH analogues are now emerging as pharmacologic agents in reproductive medicine...

BACKGROUND: Obesity is associated with several fertility disorders. This prospective cohort study was designed to evaluate the effect of body mass index (BMI) (kg/m(2)) on oocyte diameter and treatment. METHODS: Women undergoing in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI) were enrolled in the study. They were divided into two groups according to BMI: obese (BMI > 30) and normal weight (BMI < 25). Mature oocytes were evaluated according to total diameter, zona pellucida, and oolema diameters...

PURPOSE: The functional role of the FSHR promoter -29G/A polymorphism (rs1394205) in men is not clear. Some studies failed to find a relationship between the FSHR -29G/A and follicle-stimulating hormone (FSH) levels and did not associate the SNP with male infertility. Only one study showed that the FSHR -29 SNP modulates serum FSH levels in Baltic young male cohort. Because the SNP -29G/A has to be shown to have a strong effect on in vitro transcription activity of the FSHR promoter and the activation of FSHR is necessary for a normal FSH function, this study was undertaken to assess whether the FSHR -29G/A SNP modulates the gonadal endocrine function in men...

OBJECTIVE: Intracytoplasmic sperm injection (ICSI) is commonly used during pre-implantation genetic diagnosis (PGD) in vitro fertilization (IVF), aiming to eliminate the risk of contamination from extraneous sperm DNA. Recently, ICSI "overuse" in non-male infertility has been doubted, since it does not offer an advantage over IVF. Prompted by the aforementioned observations, we sought to assess the accuracy of IVF vs ICSI in PGD cases, as might be reflected by a difference in the prevalence of discarded embryos as a consequent of parental contamination...

PURPOSE: This study aims to report a case of ovarian hyperstimulation syndrome (OHSS) following GnRH agonist trigger for final follicular maturation. METHODS: This study is a retrospective chart review. RESULTS: We report the first case of OHSS following GnRH agonist trigger for final follicular maturation and freeze-all, masking extrauterine pregnancy (EUP). The present case report elucidates the feasibility of stimulating and recruiting ovarian follicles yielding mature oocytes during early pregnancy and the ability of GnRH agonist to trigger final follicular maturation during pregnancy, in the presence of high progesterone and hCG levels...

PURPOSE: This study aims to determine the optimal cryopreservation protocol for whole ovaries intended for preservation of fertility in women. METHODS: We investigated the optimal cryopreservation procedure for whole ovaries in a bovine model. The following parameters were investigated to determine their effect on ovarian tissue viability: type of cryoprotectant, administration route of the cryoprotectant (perfusion and/or submersion), and the maximum tolerable interval between death of the animal and start of the cryopreservation process...

PURPOSE: A subset of preimplantation embryos identified as euploid may in fact possess both whole and sub-chromosomal mosaicism, raising concerns regarding the predictive value of current comprehensive chromosome screening (CCS) methods utilizing a single biopsy. Current CCS methods may be capable of detecting sub-chromosomal mosaicism in a trophectoderm biopsy by examining intermediate levels of segmental aneuploidy within a biopsy. This study evaluates the sensitivity and specificity of segmental aneuploidy detection by three commercially available CCS platforms utilizing a cell line mixture model of segmental mosaicism in a six-cell trophectoderm biopsy...
