background: this study aimed to evaluate the strength of anti?mullerian hormone (amh) and follicle stimulating hormone (fsh) in reflecting the antral follicle count (afc) in infertile females. materials and methods: this cross?sectional study was conducted on 160 females, visiting infertility clinic for assisted reproduction. serum samples collected on the 3rd day of the cycle were assayed for ...

This study was undertaken to establish whether ovulation in humans alternates consistently from right to left ovary in successive cycles and whether the site of ovulation affects the next cycle length or the hormonal profiles. A total of 199 cycles in 80 normally fertile women were studied. The volunteers were monitored with ultrasonography to determine the day and side of ovulation and to calc...

This study was designed to assess the changes in nonlinear properties of heart rate (HR) variability (HRV) during the menstrual cycle by means of complexity measures, including sample entropy (SampEn) and correlation dimension (CD), and explore probable physiological interpretations for them. In 16 healthy women (mean age: 23.8 +/- 2.7 yr), complexity measures along with the spectral components...

BACKGROUND Stress and corticotropin-releasing hormone inhibit the reproductive axis. We hypothesized that reproductive axis hormone secretion, particularly luteinizing hormone secretion, is inhibited in women with depression, similar to what has been observed to be caused by stress in numerous species. METHODS Blood samples were collected every 10 minutes for 12 hours in 25 untreated premenop...

Ovarian follicle selection is an important process impacting the laying performance and fecundity of hens, and is regulated by follicle-stimulating hormone (FSH) through binding to its receptor [follicle-stimulating hormone receptor (FSHR)]. In laying hens, the small yellow follicle (6-8 mm in diameter) with the highest expression of FSHR will be recruited into the preovulatory hierarchy during...

During a normal menstrual cycle, serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol, and progesterone can vary widely between cycles for the same woman, as well as between different woman. Reliable reference values based on the local population are important for correct interpretation of laboratory results. The purpose of our study was to determine detailed ...

Objective: To compare Dehydroepiandrosterone Sulfate to Free Testosterone (DHEAS/FT) and Luteinizing Hormone to Follicular Stimulating Hormone (LH/FSH) ratios in Polycystic Ovarian Syndrome (PCOS) women. Material and Methods: The present study was done in the Department of Biochemistry in collaboration with Department of Obstetrics and Gynaecology in which 30 PCOS cases and 30 ages matched heal...

Follicular fluid (FF) provides a very important microenvironment for the development of oocyte maturation, ovulation and fertilization. The objective of this study was to determine the effect of different charged groups of cow follicular fluid proteins on in vitro oocyte maturation (IVM) when added to cultured maturation medium. The follicular fluid were obtained from dominant follicle and prec...

We have analysed the content of the growth and differentiation regulating peptide, transforming growth factor beta1 (TGFbeta1), in follicular fluid from patients undergoing in-vitro fertilization (IVF), and correlated concentrations of TGFbeta1 with the outcome of the IVF treatment and the concentrations of 17beta oestradiol in serum at ovum retrieval. A total of 88 women with infertility of >3...
