OBJECTIVE: To assess whether the presence of high DHEAS (HD) at 7 years determines different timing, sequence, and rate of pubertal events, and whether it is associated with adrenal and/or ovarian hyperandrogenism and changes in ovarian morphology throughout puberty. METHODS: In a longitudinal study of 504 girls, clinical evaluation was performed every 6 months after 7 years of age to detect Tanner stages; hormonal and anthropometric measurements were conducted at thelarche (B2), breast Tanner 4 (B4), and 1 year after menarche; ultrasonographic evaluation was also performed after menarche...

INTRODUCTION: Antimullerian hormone (AMH) strongly correlates with ovarian reserve and response to controlled ovarian stimulation. Emerging data suggests that serum AMH level may also predict ART outcomes. However, AMH is characteristically elevated in PCOS women and it is unknown whether it may predict live birth outcomes in this population. METHODS: This was a retrospective cohort study of 184 PCOS women (Rotterdam criteria) who underwent their first fresh IVF/ICSI cycle...

OBJECTIVE: To evaluate the association between diminished ovarian reserve (DOR) in women at risk of recurrent pregnancy loss (RPL) using ovarian reserve tests. DESIGN: Systematic review and meta-analysis. SETTING: University medical schools. PATIENT(S): Women with a history of RPL. INTERVENTION(S): Systematic reviews of major electronic databases (MEDLINE, EMBASE, Web of Science, and Scopus) for studies that evaluated the incidence of DOR in women with RPL...

PURPOSE: Increased serum C-protein (CRP) levels reduce fecundity in healthy eumenorrheic women with 1-2 pregnancy losses. Subclinical systemic inflammation may impede maternal immune tolerance toward the fetal semi-allograft, compromising implantation and early embryonic development. Some miscarriages with normal karyotypes could, therefore, be caused by inflammation. Whether pre-pregnancy CRP relates to karyotypes of spontaneously aborted products of conception (POCs) was investigated...

OBJECTIVE: To evaluate potential associations between concentrations of antimüllerian hormone (AMH) and T as well as the LH/FSH ratio and the unbiased precise ovarian volume obtained after unilateral ovariectomy. DESIGN: Cohort study. SETTING: University hospital. PATIENT(S): A total of 765 patients having one ovary surgically removed for fertility preservation. Inclusion criteria were age >15 years and ovarian volume <25 mL; 386 women had one or more hormone parameter (AMH, LH, FSH, or total T) determined before oophorectomy...

CONTEXT: Antimüllerian hormone (AMH) levels are higher in patients with polycystic ovary syndrome (PCOS). Accumulating evidence indicates that AMH has an impact on the physiology of the female reproductive system. OBJECTIVE: To investigate the association of AMH levels with the risk of preterm delivery in PCOS patients. DESIGN: Retrospective cohort study. SETTING: Academic fertility center. PATIENTS: Women who underwent in vitro fertilization between January 2017 and July 2018 (25,165 cycles)...

OBJECTIVE: To assess the clinical contribution of luteal-phase stimulation (LPS) to follicular-phase stimulation (FPS) in a single ovarian cycle (DuoStim) for poor responder patients fulfilling the Bologna criteria. DESIGN: Observational study (years 2015-2017) including women satisfying ≥2 of the following characteristics: maternal age ≥40 years and/or ≤3 oocytes retrieved after previous conventional stimulation and/or reduced ovarian reserve (i.e., antral follicle count <7 follicles or antimüllerian hormone <1...

Our aim was to investigate whether Antimullerian Hormone (AMH), complete blood count (CBC), Homeostasis model assessment (HOMA-IR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and weight gain have any diagnostic value for the prediction of cardiovascular disease ( CVD) in obese and non-obese pregnant patients. A prospective, case-control study was carried out, including 187 patients (93 obese, and 94 non-obese). CVD risk for each patient was evaluated according to the American College of Cardiology/American Heart Association Task Force on Practice Guidelines (ACC/AHA)...

OBJECTIVES: Information is scarce on levels of kisspeptin-1 and the kisspeptin-1 receptorin females after ovarian transplant. In this study, our aim was to explore serum estradiol, anti-Müllerian hormone, kisspeptin-1, and kisspeptin receptor levels, along with kisspeptin-1-positive cell density, in ovaries from rats after ovarian transplant. MATERIALS AND METHODS: For this study, 28 female Sprague Dawley rats were divided into 4 groups, with sham surgery performed on rats in group 1 (control group)...

OBJECTIVE: To evaluate whether superovulation improves fecundity in women undergoing therapeutic donor insemination (TDI). DESIGN: Retrospective cohort study. SETTING: University-affiliated fertility clinic. PATIENT(S): Healthy women aged 23-45 years with no history of or risk factors for infertility who underwent 152 medicated and 104 unmedicated TDI cycles from 2013 to 2018. INTERVENTION: Unmedicated TDI versus use of medication in a TDI cycle (clomiphene citrate or letrozole)...

The aim of this study was to investigate some of the growth and transcriptional factors originating from oocytes and granulosa cells in follicular fluid and to identify the relationships between the basic blood metabolite-metabolic hormones and intrafollicular lipopolysaccharide (LPS) concentrations. Thirty cows included in the study were allocated into 2 groups comprising 15 cows with healthy preovulatory follicles (cyclic cows) and 15 cows with confirmed cystic follicles. The ovaries and uteri of all cows were assessed by transrectal ultrasonographic examination...

Premature overexposure to thyroid hormone causes profound effects on testis growth, spermatogenesis and male fertility. We used genetic mouse models of type 3 deiodinase (DIO3) deficiency to determine the genetic programs affected by premature thyroid hormone action and to define DIO3 role in regulating thyroid hormone economy in testicular cells. Gene expression profiling in the neonatal testis of DIO3-deficient mice identified 5699 differentially expressed genes. Up-regulated and down-regulated genes were respectively involved according to DAVID analysis with cell differentiation and proliferation...

OBJECTIVE: To investigate whether telomere length (TL) in granulosa cells (GC) or cumulus cells (CC) correlates with TL in leukocytes (L). DESIGN: Prospective noninterventional study. SETTING: Private assisted reproductive technology center. PATIENT(S): Thirty-five egg donors were included in the study. INTERVENTIONS(S): None.
