Hypothalamic-pituitary-gonadal function was studied in 37 cirrhotic males, 25 of whom were alcoholic. Irrespective of aetiology, cirrhotic patients had significantly reduced free testosterone concentrations. Despite low free testosterone concentrations and reduced or absent spermatogenesis, basal levels of luteinizing hormone (LH) and follicle stimulating hormone (FSH) were normal in nearly all...

the objective of this study was to examine the correlation between both midfollicular fsh/lh ratio and number(s) of follicles with ovarian hyperstimulation syndrome (ohss) in patients with polycystic ovarian syndrome (pcos). this was carried out in ivf unit at mirza kouchak khan hospital. to induce ovulation, pcos patients were stimulated with gonadotropines. fifty four pcos patients with norma...

BACKGROUND The aim of this study was to investigate the predictive accuracy and clinical value of performing either a single or a repeated clomiphene citrate challenge test (CCCT) in predicting poor response in IVF, compared to that of currently used basal ovarian reserve markers. METHODS Sixty-three patients undergoing their first IVF treatment were prospectively included. After measurement ...

UNLABELLED Study Type - Diagnostic (validating cohort). Level of Evidence 2a. What's known on the subject? and What does the study add? FSH is a hormone released by the anterior pituitary gland via stimulation from gonadotrophin-releasing hormone and potentially other factors. FSH reflects the status of spermatogenesis (i.e. the ability to produce sperm) as a result of the feedback between the ...

BACKGROUND The higher prevalence of preterm birth (PTB) and low birthweight (LBW) following infertility treatment may relate to the treatment itself or indicate that subfertility predisposes to a higher risk. Our aim was to examine whether basal FSH levels are related to the risk for PTB and LBW among pregnancies resulting from IVF. METHODS We studied a retrospective cohort in the 2008 Nation...

Cimetidine is effective drugs on male reproductive system by its effect semen characteristic or parameters such as sperm motility, morphology and count, also cimetidine sexual hormones, were testosterone, FSH LH. In this investigation, 20 rats randomly classified into two groups, Control group(G1): This group contain 10 receiving normal saline group( G2): 100mg/kg. B.W. from group, during the p...

BACKGROUND It is important to differentiate central from peripheral causes of precocious puberty because of distinct management options. CASE CHARACTERISTICS 4 girls with discordant pubertal development. OBSERVATIONS All had low basal and GnRHa stimulated FSH and LH level with high estradiol level. Abdominal ultrasonogram helped in diagnosing precocious pseudopuberty- ovarian cyst in 3 chil...

PURPOSE A gonadotropin-releasing hormone stimulation test (GnRHST) is the gold standard in diagnosing central precocious puberty (CPP). The aim of this study was to investigate the diagnostic accuracy of basal gonadotropin levels for girls with suspected precocious puberty and to evaluate the factors affecting positive results of the GnRHST. METHODS Korean girls with early pubertal developmen...

BACKGROUND Since in clinical practice long-term estrogen (E) treatment is frequently applied, our aim was to study the effect of concomitant progesterone (P) administration on changes caused by long-term estrogen treatment in the secretion of LH, FSH, PRL and GH. MATERIAL/METHODS Diethylstilbestrol (DES), P or both in silastic capsules were implanted under the skin of prepubertal Sprague-Dawl...

The effect of quadruple chemotherapy (mustine, vincristine, procarbazine, and prednisolone) on gonadal function was investigated in 15 males and 2 females treated for Hodgkin's disease during childhood. The 2 females have regular menstrual cycles with evidence of ovulation in one. Twelve of the males have shown normal progression of pubertal development since completing their treatment. Nine ou...
