introduction: to determine the prevalence of oocyte pick up complications in 1120 cycles of ivf . material and methods: in this prospective study 1120 pationts that were reffered to infertility clinics for ivf were enrolled. the patients with the infertility following co4 by regimens of cc+ hmg/hcg, hmg/hcg, hmg+ gnrh-a/hcg were punctured by transvaginal sonography, preformed after injection of...

background: infected with intestinal parasites is one of the most important health and economical problems, which could have different effects, such as diarrheal diseases or death associated. the purpose of this study was to determine the level of prevalence of cryptosporidium and giardia parasites in the vegetable marketed in ilam city. methods: this study was performed on 280 samples of fresh...

In mammals, oocyte acquires a series of competencies sequentially during folliculogenesis that play critical roles at fertilization and early stages of embryonic development. In mouse, chromatin in germinal vesicle (GV) undergoes dynamic changes during oocyte growth and its progressive condensation has been related to the achievement of developmental potential. Cumulus cells are essential for t...

The electromagnetic field (EMF) has an effect on various organs, including the female reproductive system. purpose of this study was to evaluate impact carnosine ovarian follicle number and diameter in rats exposed a 900 Megahertz (Mhz) field. In study, six different groups were used. 40 divided into evaluated. ovaries removed at end study. Routine histological procedures performed tissues. Fol...

Poor oocyte quality is a main concern for decreased reproductive outcomes in women with polycystic ovarian syndrome (PCOS) during controlled ovarian hyperstimulation (COH). A primary way to improve oocyte quality is to optimize the COH protocol. It was demonstrated that the viable embryo rate per oocyte retrieved in the Utrogestan and hMG protocol, a novel regimen based on frozen-thawed embryo ...

developing a culture system for preantral follicles has important biotechnological implications due to the potential to produce a large number of oocytes for embryo production and transfer. to accomplish this goal, the present study was aimed to culture preantral follicles in the presence of different media, sera and fsh concentrations. six-week-old preantral follicles (95 ± 5 µm) were cultured...

Following early embryonic germ cell migration, oocytes are surrounded by somatic cells and remain arrested at diplotene stage until luteinizing hormone (LH) surge. Strict regulation of both meiotic arrest and meiotic resumption during dormant stage are critical for future fertility. Inter-cellular signaling system between the somatic compartment and oocyte regulates these meiotic events and det...

We hypothesized that the number of microscopic follicles present in the ovaries of cattle selected for twin births (Twinner) would be greater than in the ovaries of contemporary Controls. Ovaries were collected from seven Control and seven Twinner cows at slaughter. The number of Small (1 to 3.9 mm), Medium (4 to 7.9), and Large (> 8 mm) surface follicles was counted and one ovary was fixed for...

BACKGROUND The predictive roles of follicle stimulating hormone (FSH), anti-mullerian hormone (AMH) and antral follicle count (AFC) as ovarian reserve markers in women with different age groups are not established well. OBJECTIVE This study compares the value of FSH, AMH and AFC at the time of in vitro fertilization (IVF) treatment in different age groups. MATERIALS AND METHODS In this cros...

Abstract Background Estradiol is an important marker of ovarian response to stimulation in ART cycles. The study tries find the correlation serum estradiol on day HCG trigger number follicles, oocytes retrieved, and mature oocytes, also, correlate per follicle oocyte HCG, oocytes. It a cross sectional using retrospective data. Results data 232 patients were analyzed. Our showed positive between...
