The relative r\l=o^\lesof FSH and LH in ovulation induction in immature and adult cycling rats and hamsters have been evaluated. Both heterologous purified pituitary hormones and homologous crude pituitary extracts have been used as ovulatory stimuli in immature animals primed with PMSG. Well-characterized FSH and LH antisera have been used in the above model systems to achieve specific neutral...

Thirteen cycles of anovulation menstruation in 11 cases were treated with Electro-Acupuncture (EA) ovulation induction. In 6 of these cycles which showed ovulation, the hand skin temperature (HST) of these patients was increased after EA treatment. In the other 7 cycles ovulation was not induced. There were no regular changes in HST of 5 normal subjects. The level of radioimmunoreactive beta-en...

similar regardless of whether urinary or recombinant gonadotrophins are used. In this article the author refers to the study of Gleicher et al. (2000), which makes no comparison between urinary and recombinant products, but instead questions whether ovulation induction in general should be replaced by IVF as a means of reducing the risk of higher order multiple pregnancy. To conclude, I feel th...

background: in patients with anovulatory infertility the first choice of treatment for ovulation induction is an antiestrogen, most commonly clomiphene citrate (cc). however, 20-25% of the women are resistant to cc and do not ovulate perhaps due to antiestrogenic mechanism of the cc action, which involves long-lasting estrogen receptor (er) depletion. objective: the objective of the study was t...

discussion the presence of ohss in spontaneous pregnancy especially in familial pattern may lead us to evaluate some endogenous pathogenic factors. case presentation in this case report, we are going to present two cases of ohss occurring in spontaneously conceived pregnancies. one of the patients mentioned the history of this syndrome in her sister, and the other one confronted with this syndr...

background and purpose: the clinical outcome of intrauterine insemination (iui) treatment cycles employing a gonadotrophin-releasing hormone agonist [superfact)] or human chorionic gonadotrophin (hcg) for ovulation induction was compared. materials and methods: a group of 100 patients presenting with amenorrhoea, oligomenorrhoea or unexplained infertility were all treated with clomiphene 100 mg...

Background: Currently clomiphene citrate is the first-line treatment to induce ovulation in women with polycystic ovarian syndrome (PCOS). Surgical therapy with laparoscopic ovarian drilling (LOD) may avoid or reduce the need for gonadotropins. Objective: To determine the effectiveness and safety of LOD compared with ovulation induction in subfertile women with clomiphene-resistant PCOS. Search...

Abstract This study assessed the effects of social dominance on behavioral estrus and ovarian parameters dairy goats subjected to synchronous induction during non-breeding season. Synchronous was induced in 23 allocated collective pens. Ovarian ultrasonography performed at 12 h intervals from device removal ovulation. Upon onset (EO) detection, were immediately removed Dominance scored accordin...
