Background The effect of smoking cigarettes is followed by diverse effects on ovaries and developing follicles but the effect of passive smoking on ovarian function is unknown. On the other hand, the ovarian response to induction is a very important step in assisted reproduction. The aim of this study is to compare ovarian response in passive smokers and non-passive smokers in an assisted repro...

Oestradiol enhances pituitary sensitivity to gonadotrophin-releasing hormone (GnRH) in normal women, while in women undergoing ovulation induction the putative factor gonadotrophin surge attenuating factor (GnSAF) attenuates the response of luteinizing hormone (LH) to GnRH. To study the relationships between oestradiol and GnSAF during ovulation induction, 15 normally ovulating women were inves...

OBJECTIVE To measure the willingness to pay (WTP) of women aged 18-45 years to receive drug treatment for ovulation induction (ie, the social value of normal cycles of ovulation for a woman of childbearing age) in order to feed the debate about the funding of fertility cares. SETTING An anonymous questionnaire was used over the general population of Quebec. PARTICIPANTS A total of 136 subje...

It has been suggested recently that, in some quarters, IVF be offered as first-line therapy to all infertile couples, regardless of the type of infertility. Hence, the time was thought right to scrutinise the results and complications of ovulation induction for anovulatory infertile couples. In addition to examining the outcome of conventional treatment with gonadotrophins and clomiphene citrat...

This study reviewed the protocols for ovulation induction in sows by human chorionic gonadotropin (hCG) and gonadotropin releasing hormone (GnRH). In pigs, it was documented that ovulation usually occurred about 70% of the way through oestrus. However, the duration of oestrus in sows highly varies, producing difficulty in performing artificial insemination (AI) in sows at optimal time. In pract...

Letrozole, an aromatase inhibitor, has been demonstrated to be effective as an ovulation induction and controlled ovarian hyperstimulation agent. However, dose administration has generally been limited to 5 days at 2.5 to 7.5 mg daily. We undertook a retrospective review of over 900 treatment cycles using letrozole in doses as high as 12.5 mg per day. Results indicate that such doses do indeed ...
