background: diabetic men have been claimed to have lower serum free testosterone (ft) concentrations than non-diabetic men. the aim of this study was to investigate if serum ft, luteinizing hormone (lh), and follicle stimulating hormone (fsh) concentrations are different in patients with type 2 diabetes mellitus compared with healthy men and to identify factors associated with low serum testost...

In ovarian antral follicles cumulus cells (approximately 1,000/follicle) closely surround the oocyte, and mural granulosa cells (approximately 50,000/follicle) are distributed at the periphery. Previous work (Salustri, A., Yanagishita, M., and Hascall, V. C. (1990) Dev. Biol. 138, 26-32) showed that oocytes produce a factor(s) which stimulates hyaluronic acid (HA) synthesis by cumulus cells dur...

background: estradiol (e2) is required for follicular development and play an important role in embryo implantation. objective: the aim of this study was to assess the impact of serum e2 levels on the day of hcg administration in ivf-icsi patients who are performed controlled ovarian hyperstimulation (coh). materials and methods: a total of 203 women who were undergone one time ivf cyclus were ...

OBJECTIVE To compare the effectiveness of an electrocautery strategy with ovulation induction using recombinant follicle stimulating hormone in patients with polycystic ovary syndrome. DESIGN Randomised controlled trial. SETTING Secondary and tertiary hospitals in the Netherlands. PARTICIPANTS 168 patients with clomiphene citrate resistant polycystic ovary syndrome: 83 were allocated elec...

Background: Follicle stimulating hormone is a heterodimeric protein composed of two subunits, α and ß, which are linked noncovalently. The hypophysial gonadotropin FSH plays an important role in the regulation of oocyte maturation, and a key component for growth of ovulator follicles in ewes. Materials and Methods: This study seeks to clone and express the ovine follicle stimulating hormone sub...

background: the predictive roles of follicle stimulating hormone (fsh), anti-mullerian hormone (amh) and antral follicle count (afc) as ovarian reserve markers in women with different age groups are not established well. objective: this study compares the value of fsh, amh and afc at the time of     in vitro fertilization (ivf) treatment in different age groups. materials and methods: in this c...

the present study aimed at investigating the beneficial effects of co-administering granulocyte colony–stimulating factor (g-csf) and stem cell factor (scf) in a model of chronic liver injury induced by thioacetamide (taa). biochemical and histopathology- cal examinations were performed on serum and liver specimens. at the end of the treatment period, the rats were anesthetized with ether, seru...
