Women in cities are less likely to have babies

Women are less likely to procreate in urban areas that have more women than men in the population. Although the majority of modern cities have that statistic and thus suffer from lower fertility rates, the effects of female-biased sex ratios – having more women than men in a population – is less studied than male-biased ratios. A new study in Behavioral Ecology, published by Oxford University Press analysed how female-biased sex ratios are linked to marriages, reproductive histories, dispersal, and the effects of urbanisation on society. The research team from the University of Turku, University of Helsinki, and Pennsylvania State University used a massive internal migration event that occurred in Finland during WWII, when 10 per cent of Finnish territory was ceded to the Soviet Union and over 400,000 citizens were evacuated. The Finnish government implemented a settlement act to …

A new study has suggested that men are sensitive to the odour that women emit while they are sexually aroused or interested in sex. The study was published in the journal – Archives of Sexual Behavior. University of Kent research suggests that men can distinguish between the scents of sexually aroused and non-aroused women. This research by Dr Arnaud Wisman, a Psychologist at the University of Kent, expands on previous studies which have concluded that humans can communicate and detect emotions such as fear or sadness through scent. Sexual arousal is also identified as an emotional physical state. Findings were established through three different experiments where men processed the scents of axillary sweat samples from anonymous sexually aroused and non-aroused women. Men evaluated the scent of sexually aroused women as relatively more attractive and this increased their sexual motivation. This …

Solving chronic pain during intercourse

By identifying what triggers the pain in the female reproductive tract, researchers at Flinders University are working for a remedy on pain during intercourse. Dr Joel Castro Kraftchenko – Head of Endometriosis Research for the Visceral Pain Group (VIPER), with the College of Medicine and Public Health at Flinders University – is leading research into the pain attached to Dyspareunia, also known as vaginal hyperalgesia or painful intercourse, which is one of the most debilitating symptoms experienced by women with endometriosis and vulvodynia. Pain is detected by specialised proteins (called ion channels) that are present in sensory nerves and project from peripheral organs to the central nervous system. “Very little is known about which ion channels are in charge of detecting painful stimuli from the female reproductive tract; and how pain is transmitted via peripheral sensory nerves (innervating these organs) …
