Hypothyroidism denotes deficient production of thyroid hormone by the thyroid gland and can be primary (abnormality in thyroid gland itself) or secondary/central (as a result of hypothalamic or pituitary disease). The term 'subclinical hypothyroidism' is used to define that grade of primary hypothyroidism in which there is an elevated thyroid-stimulating hormone (TSH) concentration in the prese...

Subclinical hypothyroidism, which is defined as elevated thyroid-stimulating hormone (TSH) levels with free thyroxine concentrations within the reference range, is a common disorder that increases with age and affects up to 18% of the elderly, with a higher prevalence in women compared to men. Prospective data have shown an increased risk of coronary heart disease events, heart failure, and car...

background: the beneficial role of cabergoline as a prophylactic agent to prevent ovarian hyper stimulation syndrome (ohss) among high-risk patients has been demonstrated in previous studies. but data for its role as a treatment for established severe ohss is still limited. we represent the treatment results of high dose oral cabergoline in management of six patients after the syndrome is estab...

background: gonadotrophin-releasing hormone (gnrh) agonist is used for controlling ovarian stimulation in assisted reproductive technology (art) cycles which has some benefits. objective: to compare the efficacy of two different formulations of gnrh agonist: short-acting and long-acting, for art protocols. materials and methods: in a prospective randomized study, one hundred women who underwent...

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 ...

background: smoking has negative effects on reproductive process. exposing to cigarette smoking (passive smoking) may exert some effects as the direct smoking. objective: the aim of this study was to evaluate the correlation between ovarian response and passive smoking in women who underwent art cycles. materials and methods: one hundred-sixty patients who underwent icsi between 2000 and 2001 w...

background: although the uterine fibroids are common, their influence on fertility remains controversial. the association of submucosal fibroid with subfertility is well recognized, but debate persists as to whether intramural fibroids can cause infertility and the evidence for its effect on pregnancy in cycles of assisted conception remains unclear. objective: the purpose of present study was ...

background: careful evaluation of patients and proper treatment with right techniques are essential for successful outcome of assisted reproduction. to obtain satisfactory results, it is necessary to assess ovarian reserve before planning treatment. objective: to evaluate anti-mullerian hormone as a predictor of fertility potential in terms of ovarian reserve and ovarian response reflected by a...

this study was undertaken to compare the efficiency of fresh and frozen-thawed buck semen on in vitro fertilization (ivf) of goat oocytes. cumulus oocytes complexes (cocs) were collected by aspiration of 2-6 mm diameter follicles, which were obtained from slaughterhouse. upon grading, only normal quality cocs were maturated in tcm-199 for 48 hours. the percentage of cocs reached to the m-ii sta...
