background: the luteal phase defect is a common event following the ovarian stimulation. the aim of the present study was to evaluate the use of human chorionic gonadotropine (hcg) and progesterone hormones to improve the luteal phase defect. materials and methods: 60 mice were superovulated routinely with human menopausal gonadotropin (hmg) (7.5u) and hcg (10u). the mice were mated and divided...

Multiple pregnancies and ovarian hyper stimulation syndrome (OHSS) are the most serious complications of ovarian stimulation and IVF. Indeed, they are more or less the only ones. OHSS can effectively be prevented in three stages: Before stimulation, during stimulation and at ET. Before stimulation patients should be assessed as to age, the ovarian follicular count and/or anti mullerian hormone ...

background: based on classical two-cell, two-gonadotropin theory, in the follicle, follicle-stimulating hormone (fsh) and luteinizing hormone (lh) put on their main effects on the granulosa and theca cells. lh is essential for androgens production. androgens are used for estradiol production by granulosa cells. profound suppression of lh concentrations in some normogonadotropic patients can cau...

objective: to evaluate the impact of luteal phase support with vaginal progesterone on pregnancy rates in the intrauterine insemination (iui) cycles, stimulated with clomiphene citrate and human menopausal gonadotropin (hmg), in sub fertile couples. materials and methods: this prospective, randomized, double blind study was performed in a tertiary infertility center from march 2011 to january 2...

Background O-30: The Correlation between Myometrial Thickness and In Vitro Fertilization/ Intracyto- Plasmic Sperm Injection (IVF/ ICSI) Outcomes MaterialsAndMethods In this prospective cohort study, 453 infertile women undergoing IVF-ET/ICSI cycles without any obvious pathology of uterine were enrolled. Trans-vaginal ultrasounds were conducted on days 2-4 of the cycle (menstrual phase) precedi...

background: gnrh agonist administration in the luteal phase has been suggested to beneficially affect the outcome of intracytoplasmic sperm injection (icsi) and embryo transfer (et) cycles. this blind randomized controlled study evaluates the effect of gnrh (gonadotropine releasing hormone) agonist administration on icsi outcome in gnrh antagonist ovarian stimulation protocol in women with 2 or...

background: this research investigated the response of vascular active factors, vascular endothelial growth factor (vegf) and angiotensin-ii (at-ii) to ovarian stimulation during 24 hours in patients with polycystic ovary syndrome (pcos). materials and methods: in this clinical trial study, 52 patients with pcos and 8 control cases were stimulated with human chorionic gonadotropin (hcg) on the ...

background: acceptance of uterus and reaction between endometrium and embryo has an important role for implantation. muc1 an integral membrane mucin is expressed on the apical surface of uterine epithelial cells and could have effects on its receptivity. objective: the aim of this study was to evaluate the changes in muc1 expression of gravid mouse endometrium with and without hyperstimulation ...

background: the preparation of endometrium for embryo reception is dependent on the ovarian hormones, which are affected by ovarian hyperstimulation procedure. objective: the aim of this study was to evaluate the changes in morphometrical indices of endometrium by the daily injection of progesterone after mouse ovarian induction. materials and methods: adult virgin female mice were selected and...
