combination therapy with clomiphene citrate plus gonadotropin (clomiphene citrate plus hmg) in induction ovulation reduce the gonadotropins dose but antiestrogenic effect of c.c. can decrease pregnancy rate. in a randomized clinical trial we compared 3 treatment protocol for induction ovulation and intra uterine insemination (i/o plus iui) in women with infertility history more than one year, n...

BACKGROUND Sex-related differences in the severity of multiple sclerosis (MS) could be influenced by the sex hormones. MATERIALS AND METHODS This cohort (historical) study evaluated the sex hormone levels during menstrual cycle and their correlation with disease severity in MS. RESULT Patients with MS had significantly lower testosterone, dehydroepiandrosterone sulfate and prolactin levels ...

In response to previously published evidence from monkeys, this study examined the influence of the degree of luteinizing hormone (LH) suppression during the follicular phase of the stimulation cycle, upon cryopreserved embryo survival and development. The LH concentration of the mid-follicular phase was assessed in 250 in-vitro fertilization (IVF) cycles treated with gonadotrophin-releasing ho...

BACKGROUND Testosterone levels have been linked to life expectancy in men, less is known about the sex hormones follicular stimulating hormone and luteinizing hormone. AIM To examine the association of testosterone, follicular stimulating hormone, luteinizing hormone with mortality. DESIGN Prospective cohort analysis. METHODS Participants were 4255 Vietnam-era US army veterans with a mean...

The research was intended for studying the association between follicular size and some hormonal ionic compounds fluid with oocyte development in ovaries of local goats (Capra hircus), period from September 2020 to March 2021 department Animal Production techniques at Al-Musaib Technical College. 150 genital organs were gathered adult non –pregnant female (does), which slaughtered Babylon provi...

routinely, a bolus of 5.000-10.000 iu human chorionic gonadotropin (hcg) is usedfor the final follicular maturation and ovulation as a standard method. hcg has thesame effect of luteinizing hormone (lh) with long half-life. it has the longlutheotrophic effect which increases the risk of ovarian hyper stimulation syndrome(ohss). recently, gonadotropin-releasing hormone agonist (gnrh-a) trigger h...

BACKGROUND The aim of this study was to develop a mathematical model of the hypothalamo-pituitary-gonadal axis that would reflect available data in humans. METHODS A model of hormonal relationships at the early follicular and midluteal phases of the human menstrual cycle is proposed. FINDINGS Two distinct temporal patterns of oscillatory behavior have been demonstrated for both pituitary an...

background: polycystic ovary syndrome (pcos) is a disorder in which there are numerous benign cysts that form on ovaries under a thick white covering that is one of the causes of infertility. follistatin is a single chain glycosylated polypeptide that can bind to activin. when follistatin binds to activin it suppresses the role of activin to stimulate the secretion of follicle stimulating hormo...

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...

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...
