OBJECTIVE: To examine the relationship between the day of embryo cryopreservation and large for gestational age (LGA) infants in women undergoing frozen embryo transfers (FETs) after cryopreservation on days 2-7 after fertilization and to c…
OBJECTIVE: To evaluate the relationship between hysterectomy with and without ovarian conservation and the onset of ovarian failure using anti-müllerian hormone (AMH) levels and imputed final menstrual period (FMP). METHODS: A total of 1,4…
BACKGROUND: A test that helps predict the time to the final menstrual period (FMP) has been sought for many years. OBJECTIVE: To assess the ability of antimullerian hormone (AMH) measurements to predictions the time to FMP. DESIGN: Prospe…
CONTEXT: The relationship between reproductive and cardiometabolic aging is unclear. It is unknown if the relationship differs across different clinical populations. OBJECTIVE: To determine whether markers of ovarian reserve are associated…
STUDY QUESTION: Are intrauterine insemination (IUI) performance characteristics and post-processing total motile sperm count (TMC) related to live birth rate in couples with unexplained infertility? SUMMARY ANSWER: Patient discomfort with …
OBJECTIVE: To study whether there is a difference in the prevalence of non-cavity-distorting uterine fibroids between infertile patients with polycystic ovary syndrome (PCOS) and those with unexplained infertility (UI). DESIGN: A secondary…
OBJECTIVE: Endometriosis is a chronic, estrogen dependent condition that affects 5-10% of reproductive aged women and is associated with pelvic pain and infertility. As the approach to therapy shifts from surgical ablation to pharmacologica…
Perimenopause, or the menopausal transition, represents a period of time during which newly arising symptoms can present complex management decisions for providers. Many women present to care with complaints of hot flashes, vaginal and sexu…
STUDY QUESTION: Does fertility-related quality of life (FertiQOL) differ by infertility diagnosis between women with polycystic ovary syndrome (PCOS) and their partners, compared with couples with unexplained infertility (UI)? SUMMARY ANSW…
PURPOSE: A symbiotic relationship between ovarian granulosa cells (GC) and the developing oocyte is critical. Genetic modulations in GC's can lead to reproductive insufficiency, highlighting the role of GC's in reproductive competence. Util…
OBJECTIVE: To better understand the site and mode of action of aromatase inhibitors. DESIGN: Prospective study. SETTING: Academic research environment. PATIENT(S): Five eumenorrheic (without polycystic ovary syndrome), early follicular p…
OBJECTIVE: To evaluate whether ethnicity is associated with involuntary childlessness and perceived reasons for difficulties in becoming pregnant. DESIGN: Cross-sectional analysis of baseline data from a longitudinal cohort. SETTING: Mult…
OBJECTIVE: To investigate if a diagnosis of diminished ovarian reserve (DOR) is associated with a differential gene profile of ovarian granulosa cells (GCs) in infertile women undergoing in vitro fertilization (IVF). DESIGN: Prospective Co…
OBJECTIVE: To evaluate whether adolescent obesity is associated with difficulties in becoming pregnant later in life. DESIGN: Cross-sectional analysis of baseline data from a longitudinal cohort. SETTING: Multiethnic, community-based obse…
MicroRNAs (miRNAs), a class of small noncoding RNAs that regulate gene expression, have fundamental roles in biological processes, including cell differentiation and proliferation. These small molecules mainly direct either target messenger…
BACKGROUND: In-vitro fertilization (IVF) with blastocyst as opposed to cleavage stage embryos has been advocated to improve success rates. Limited information exists on which to predict which patients undergoing blastocyst embryo transfer (…
BACKGROUND: In mouse endometrium, glycogen synthase kinase-3beta (GSK3beta) is a key enzyme controlling nuclear localization of cyclin D1. We developed a functional model of xenografted human endometrium to test whether similar mechanisms a…
OBJECTIVE: To determine if attempts to maximize oocyte yield during ovarian stimulation translates into improved outcome of in vitro fertilization (IVF) cycles. DESIGN: Retrospective study. SETTING: Academic tertiary care IVF center. PAT…
