Our aim was to examine the influence of BMI on the live-birth rate following IVF/ICSI and evaluate its specific contribution among other factors thus enabling accurate reproductive policy development. All patients that underwent IVF/ICSI at our center during January 2012-July 2015 were included in this retrospective study. A total of 1654 ICSI cycles were divided into four groups according to the patient's BMI (kg/m(2)): group I (normal weight): <25 (943 cycles); group II (overweight): 25-30 (403 cycles); group III (obese): 30-35 (212 cycles); group IV (morbid obesity): >35 (96 cycles)...

STUDY QUESTION: Does a short abstinence period of only 2 h yield spermatozoa with better motility characteristics than samples collected after 4-7 days? SUMMARY ANSWER: Despite lower semen volume, sperm concentration, total sperm counts and total motile counts, higher percentages of motile spermatozoa with higher velocity and progressiveness were detected in samples obtained after 2 h. WHAT IS KNOWN ALREADY: Most studies that have assessed the effect of abstinence periods on sperm motility parameters in men with a sperm concentration below 15 million/ml have detected a higher percentage of motile spermatozoa in samples obtained after short abstinence periods...

Application of assisted reproductive technology in camelidea, such as artificial insemination (AI) and embryo transfer, has been slow in comparison to that for other livestock species. In Egypt, there are few attempts to establish in vitro maturation (IVM) and fertilization (IVF) techniques in dromedary camel. The present study was carried out to produce Sudanese camel embryos using in vitro matured oocytes and epididymal spermatozoa. Dromedary camel ovaries were collected from abattoirs and then, the oocytes were aspirated from all the visible follicles on the ovarian surface (~2-8 mm in a diameter)...

High endometrial receptivity in the window of implantation (WOI) is essential for successful implantation. However, a diagnostic tool with high specificity for impaired endometrial receptivity remains to be developed. We collected endometrium specimens during the WOI from patients with RIF and women who conceived after one IVF/ICSI attempt. We conducted mRNA microarray on the samples followed by relevant comparative and functional analysis. Microarray analysis revealed 357 dysregulated mRNAs between the two groups...

Cycles with progesterone elevation during controlled ovarian stimulation (COS) for IVF/ICSI are commonly managed with a "freeze-all" strategy, due to a well-recognized detrimental effect of high progesterone levels on endometrial receptivity. However, also a detrimental effect of elevated progesterone on day-3 embryo quality has recently been found with regards to top quality embryo formation rate. Because blastocyst culture and cryopreservation are largely adopted, we deemed relevant to determine whether this detrimental effect is also seen on blastocyst quality on day 5-6...

Infertility problem involves many couples of reproductive age. It has been estimated that in Poland 0.7-1.0 million pairs require treatment, while for more than half of them assisted reproduction is the only recommended and effective method. Infertility affects 13 to 15% of the world's population. A major concern is the age-related decline in female fertility even more that often a decision about pregnancy is taken at later age. Recent studies show that increased production of reactive oxygen species is an important factor in etiopathogenesis of pregnancy and affects female reproduction...

The objective of our present study was to determine the effects of insulin-like growth factor I (IGF-I) on the development of yak (Bos grunniens) embryos after cumulus-oocyte complex (COC) vitrification and warming followed by in vitro fertilization (IVF). In Experiment 1, the yak COCs underwent vitrification and then IVF. Embryos were incubated in synthetic oviductal fluid (SOF) supplemented with four concentrations (0, 50, 100 and 200 ng/ml) of IGF-I, while the yak COCs without vitrification or IGF-I supplementation acted as the control group; the BAX, BCL-2, AQP3mRNA and aquaporin 3 (AQP3) protein expression levels in the five groups of blastocysts were evaluated using quantitative real-time PCR and immunofluorescence analyses...

STUDY QUESTION: Is supraphysiologic estradiol (E2) an independent predictor of low birth weight (LBW) in singletons born after fresh IVF-embryo transfer (ET) cycles? SUMMARY ANSWER: Our results suggest that E2 > 2500 pg/ml is an independent predictor for LBW in full-term singletons born to normal responder patients undergoing fresh IVF-ET cycles. WHAT IS KNOWN ALREADY: The pathogenesis of LBW in IVF singletons remains unknown. However, recent studies have suggested that the hyperestrogenic milieu generated during ovarian stimulation may create a sub-optimal peri-implantation environment, leading to placental dysfunction, and therefore, LBW...
