Climaxing may be the high point of sex for a good portion of the sexually active population, but for about 80 percent of women and 28 percent of men (yes, they can have difficulty too), the orgasm remains elusive. While failing to reach the big “O” is often chalked up to psychological reasons, such as stress or anxiety, a recent study has found that the problem lies more in the body than the mind for some.

NBC News exclusive: Uterine transplant couple speaks out

Chinese Scientists Genetically Modify Human Embryos for the Second Time
Scientists in China have reported genetically modifying human embryos in what is only the second published experiment of its kind. Last year, a different team of Chinese researchers edited human embryos in an attempt to remove genes responsible for a dangerous blood disorder. In this new research, scientists from Guangzhou Medical University tried to add a mutation to embryos instead, attempting to make them HIV-resistant. In both cases, the experiments were only partially successful, and were carried out using non-viable human embryos that were incapable of growing into adults.
Infertility Linked to Higher Birth Defect Risk
As assisted reproductive technologies (ART) treatments have developed, treatments like in vitro fertilization (IVF) have become more accessible to a wider population. Accordingly, the number of women using fertility treatments to conceive has increased such that in 2012, roughly 1.5 percent of all liveborn infants in the United States were conceived using some method of ART.

Utah Woman With Rare Infertility-Causing Disease Faces Challenges with Hope

Y Chromosome Study Suggests Neanderthals Suffered From Fertility Issues
The first examination of a long-extinct Neanderthal’s Y chromosome suggests that fertility problems may have prevented Neanderthal men from successfully mating with modern human females, researchers said.
Women With PCOS May Have Higher Asthma Rates
Survey data from more than 8,000 women revealed a higher prevalence of asthma in women who had PCOS compared with women who did not have PCOS (15.2% versus 10.6%, P=0.004), and this relationship persisted even after adjustments for weight, Anju Joham, MBBS, of Monash University in Melbourne, and colleagues, reported at the annual meeting of the Endocrine Society.
