High Levels of DNA Fragmentation in Spermatozoa Are Associated with Inbreeding and Poor Sperm Qualit
Our findings suggest that the link between inbreeding and semen quality is mediated by the effects of inbreeding upon sperm DNA damage. The deleterious effects of inbreeding upon the paternal genome likely decrease male fertility and may cause geneti
Effects of Low Methyl Donor Levels in Culture Medium During Mouse Follicle Culture on Oocyte Imprint
In conclusion, restriction of methyl donors during follicle culture led to a dramatic decrease in PB oocyte rate but induced no or only minor DNA methylation alterations at the studied regulatory sequences of key imprinted genes in oocytes.
Study of aneuploidy and DNA fragmentation in gametes of patients with severe teratozoospermia
The rate of DNA fragmentation was significantly higher in infertile patients than in the controls (P<0.001: 14.3 versus 1.20, respectively) but presented important variability. Therefore, ICSI should not be attempted if men have macrocephalic gametes
Spermatozoal RNA profiling towards a clinical evaluation of sperm quality
Therefore, spermatozoal RNA profiling may enable a better understanding of what is contributed to the oocyte by sperm, in addition to their genome, to facilitate early embryonic development.
Circulating concentration of stem cell factor in serum of stimulated IVF patients
From the day of FP to the day of confirmation of pregnancy, the SCF concentrations increased significantly and reached their highest concentration (P=0.02) during gestation. We conclude that SCF is involved in follicle development and may be a predic
Theoretical and experimental basis of slow freezing
Progress in vitrification has overshadowed slow freezing to such an extent that it has been suggested that vitrification could soon become the exclusive cryopreservation choice in human IVF. However, recent studies have clearly indicated that human e
Female gender pre-selection by maternal diet in combination with timing of sexual intercourse
It is concluded that the combination of maternal diet with timing of intercourse is capable of increasing the probability of conceiving a girl (P=0.005). The observed percentage of female babies for all 32 women satisfying the prediction rule was 81
Obstetric outcome after in vitro fertilization with single or double embryo transfer
Children born after IVF had a poorer obstetric outcome compared with children from the general population. Singletons, when analysed as one group, irrespective of whether the children were born after eSET, non-eSET or DET, also had a poorer obstetric
Salivary testosterone concentrations in pubertal ICSI boys compared with spontaneously conceived boy
At the age of 14 years, pubertal ICSI boys show testosterone levels comparable to their peers born after SC. ICSI adolescents fathered from men with severely compromised spermatogenesis show testosterone levels comparable to those from fathers with n
Multi-marker assessment of ovarian reserve predicts oocyte yield after ovulation induction.
CONCLUSIONS A derived estimate of ovarian reserve demonstrated superior ability for predicting oocyte yield after ovulation induction when compared with any single endocrine marker (AMH, inhibin B, FSH).
Prediction of sperm retrieval in men with non-obstructive azoospermia using artificial neural networ
ANNs improve the prediction accuracy of sperm retrieval. Although the leptin AUC is low, combined use of leptin and FSH can significantly improve the prediction accuracy for sperm recovery in NOA patients. Leptin may be a good assistant marker for di
Intrauterine exposure to mild analgesics is a risk factor for development of male reproductive disor
There was an association between the timing and the duration of mild analgesic use during pregnancy and the risk of cryptorchidism. These findings were supported by anti-androgenic effects in rat models leading to impaired masculinization. Our result
The successful use of pronuclear embryo transfers the day following oocyte retrieval.-(Scotts origin
The data show that oocyte quality and pronuclear embryo morphology are related to implantation and that pronuclear embryos can be successfully selected for embryo transfer.
Hydrogen Peroxide Modifies Human Sperm Peroxiredoxins in a Dose-Dependent Manner — Biology of Repr
This first study, to our knowledge, on PRDXs in human spermatozoa indicates that PRDX1, PRDX4, PRDX5, and PRDX6 are modified when spermatozoa are challenged with H2O2. This suggests that PRDXs may protect these cells at high levels of H2O2 but could
BioNews - Women should be given better fertility information, suggests report
The review says basic information about pregnancy including contraception, normal cycles, the dangers of sexually transmitted diseases and age-related risks should be reinforced through schools, family planning and sexual health clinics and the media
Do humans advertise their fertility? - Science Show - 29 January 2011
Many mammals advertise their fertility to the opposite sex in a period, when for dogs, they are referred to as being on heat. So does the same thing happen in humans? Until recently, it was thought not. But work with lapdancers has revealed an increa
University Students Sperm Donations Rise in Recession - DailyFinance
With college tuition and fees up more than 440 over the past 25 years, according to the Center for Public Policy and Higher Education, it's not surprising that students are trying to make a buck any way they can. But jobs are harder to come by in the
