background: research supports that in vitro fertilization causes anxiety and that anxiety can continue into the resulting pregnancy. most women who have ivf will have a less invasive treatment for infertility prior to ivf; however, it is unclear if specific less invasive treatment cycles impact anxiety that is experienced in the pregnancy resulting from ivf. methods: a prospective study was con...

introduction: the aim of this study was to evaluate the expression of pinopodes as animplantation marker after ovarian hyper stimulation and progesterone injection using scanningelectron microscopic studies. material and methods: three groups of nmri adult female mice were used in the experiment. the control group (group a) were untreated pseudopregnant mice. group b mice were made pseudopregna...

STUDY HYPOTHESIS Maternal ageing and ovarian stimulation result in the accumulation of mitochondrial DNA (mtDNA) deletions and heteroplasmy in individual oocytes from a novel bovine model for human assisted reproductive technology (ART). STUDY FINDING The levels of mtDNA deletions detected in oocytes increased with ovarian ageing. Low levels of mtDNA heteroplasmy were apparent across oocytes ...

BACKGROUND Poor ovarian response to controlled ovarian stimulation is one of the most important interest points in assisted reproduction. Mild ovarian stimulation seems to be preferable to high dose of FSH regimens in women with a history of poor ovarian response in previous protocol. Clomiphene citrate and letrozole alone or in combination with FSH have been used in mild ovarian stimulation pr...

PURPOSE To compare serum anti-Mullerian hormone (AMH) levels on the seventh day of ovarian stimulation between normal and poor responders. METHODS Nineteen women aged ≥35, presenting with regular menses, submitted to ovarian stimulation for assisted reproduction were included. Women with endometriosis, polycystic ovarian syndrome or those who were previously submitted to ovarian surgery were ...

The present experiments examined the effects of electrical stimulation of the superior ovarian nerve (SON) and the ovarian plexus nerve (OPN) on the ovarian estradiol secretion in rats. The rats were anesthetized on the day of estrus, and the ovarian venous blood was collected intermittently. The secretion rate of estradiol from the ovary was calculated from differences in the estradiol concent...

In-vitro maturation is a technique used to perform assisted reproduction in women with high ovarian reserve, who are at risk for ovarian stimulation. With this technique occasionally 3-4 days of gonadotropins are planned to enlarge the follicles and aid in oocyte collection. Human choreinonic gonadotropin is also given to ease the collection. These few days of ovarian stimulation were felt to b...

Ovarian stimulation for assisted reproductive technology is traditionally started in the early follicular phase. The essential rationale to allow timely follicle growth and oocyte pick up ensure synchronization of vitro cultured embryos with receptive period endometrium a fresh transfer cycle. Also, conventional thought suggested that recruitment happened only once around menstruation. Deeper u...

background: apoptosis is a process that plays an important role during early stage of implantation. the aim of this study was to investigate the incidence of apoptosis in mice endometrium after ovarian stimulation at implantation period. methods: nmri female mice were divided into two groups: 1) control group, which were rendered pseudopregnant by vaginal stimulation and 2) experimental group, ...

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...
