PURPOSE: This retrospective cohort study evaluated the cumulative live birth rate in women with polycystic ovary syndrome (PCOS) and isolated polycystic ovaries (PCO) undergoing in-vitro fertilisation (IVF) treatment. METHODS: We studied 1…

PURPOSE: Estrogen metabolizing gene mutations can be associated with defective hormonal signaling leading to disease processes. Endometriosis is an estrogen dependent that can be influenced by defective signaling in the estrogen pathway. O…

PURPOSE: To examine the impact on development of derived embryos from smooth endoplasmic reticulum clusters (SERC) in human metaphase II (MII) oocytes. METHODS: Retrospective analysis at Kyono ART Clinic. Comparison of embryological develo…

PURPOSES: Embryo quality is associated with successful implantation and live births. Our retrospective study was carried out to determine whether or not cleavage stage embryo quality affects the miscarriage rate, pregnancy complications and…

PURPOSE: To assess the impact of peritoneal endometriosis on oocyte and embryo quality in a mouse model. METHODS: Peritoneal endometriosis was surgically induced in 33 B6CBA/F1 female mice (endometriosis group, N = 17) and sham-operated we…

PURPOSE: To explore the effect of group culture on the developmental potential of discarded embryos in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles and establish the human embryonic stem cell lines for future re…

PURPOSE: The present study evaluates health status and its relation with occupational characteristics and with burnout syndrome among embryologists. METHODS: A cross-sectional design was used to conduct an online self-assessment survey, se…

PURPOSE: To determine whether Aβ40 levels in the follicular fluid (FF) of infertile women undergoing IVF demonstrate a relationship with IVF cycle parameters and outcome. METHODS: FF Aβ40 levels were compared between patients achieving ong…

OBJECTIVE: To investigate the association of basal testosterone (T) levels with the outcome of in vitro fertilization (IVF) in women with diminished ovarian reserve (DOR). METHODS: Complete clinical data on the first 223 IVF cycles in wome…

PURPOSE: We retrospectively examined a large cohort of females who underwent single blastocyst transfer to determine if initial β-human chorionic gonadotrophin (β-hCG) levels on day 7 after single vitrified-warmed blastocyst transfer (SVBT)…

PURPOSE: To evaluate the ovarian response to controlled ovarian hyperstimulation (COH) in cancer patients according to an age-specific nomogram for the number of retrieved oocytes. METHODS: Retrospective observational study carried out in …

PURPOSE: To validate the use of the ovarian sensitivity index (OSI) as a measure of ovarian response during in-vitro fertilization (IVF) treatment. METHODS: This is a retrospective study carried out in an assisted reproduction unit in a te…

PURPOSE: To assess how patients perceive various lifestyle behaviors impact IVF success. METHODS: Cross-sectional study of heterosexual, English-speaking couples (n = 138) who completed web-based surveys during IVF treatment cycle. Perceiv…

PURPOSE: To determine if etiology of infertility modifies the relationship between the duration of ovarian stimulation and success during assisted reproductive technology (ART) cycles. METHODS: A prospectively collected database was analyz…

PURPOSE: To identify the independent predictors of live birth following IVF, and to assess the role of cohort-specific parameters, including antral follicle count (AFC), the number of oocytes retrieved, the total number of embryos, and the …

PURPOSE: Growth differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15) play crucial roles in follicular development and oocyte maturation. This study aimed to investigate and compare the expression of these proteins in ov…

OBJECTIVE: To investigate the serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), monocyte chemotactic protein-1 (MCP-1), and Paraoxonase-1 (PON-1) during fertility treatment of women with endometriosis (Endo), PCOS o…

PURPOSE: To investigate the predictive value of the motile sperm organelle morphology examination (MSOME) on embryo morphology. METHODS: The morphologies of 540 embryos obtained from 60 couples undergoing ICSI were evaluated from days 1 to…

PURPOSE: Polycystic ovary syndrome (PCOS) is associated with oxidative stress (OS) and serum superoxide dismutase (SOD) activity has been reported with mixed results. The objective of this study was to examine the activity of SOD both in th…

PURPOSE: One of the most common problems in reproductive medicine is recurrent miscarriage (RM). There is increasing evidence showing genetic susceptibility of women is an important risk factor in the occurrence of RM. In recent years, ther…

PURPOSE: To compare ages of mothers and of fathers at delivery in couples who are fertile, subfertile, and subfertile treated with assisted reproductive technology (ART) and to characterize birth outcomes in the ART population according to …

PURPOSE: To determine whether Brazilian egg donation treatment outcomes with oocytes donated from infertile couples are equivalent to those obtained worldwide with oocytes donated from fertile egg-donors. METHODS: In this descriptive study…
