It is becoming increasingly difficult to avoid exposure to man-made endocrine disrupting chemicals (EDCs) and environmental toxicants. This escalating yet constant exposure is postulated to partially explain the concurrent decline in human fertility that

Flight-fecundity tradeoffs in wing-monomorphic insects
Advances in Insect Physiology, 2019Winged insects often spend considerable amounts of energy in flight, searching for food, escaping predators, and dispersing. In females, flight is hypothesized to reduce resources available for egg production, thus leading to a tradeoff between flight ...

Epidemiology, 1998
Animal studies have shown evidence of prenatal hormonal interaction between unlike sexed fetuses, including reduced fertility among females. We evaluated whether the fecundability of female twins is different from that of singletons and whether it differs according to the sex of the co-twin.

Studies in Family Planning, 1980
The current hypothesis that malnutrition impairs fecundity has recently been challenged by a number of investigations that examined the nutrition fecundity link. The controversy is important because of the potential implications for food aid programs for developing countries. If improving nutrition improves increases birth rates this would exacerbate

This multicentre study has produced a database of 7017 menstrual cycles contributed by 881 women. It provides improved knowledge on length and location of the "fertile window" (identified as of up to 12 days duration) and the pattern and level of daily conception probability.

Abstract Anthony Price has written a subtle, vivid, and engaging book. His prose might be described as mandarin with muscle (I quote a characteristic sentence: ‘Various interpreters offer a variety of turns of phrase … that, for all their felicity, seem rather to sheathe the problem than to bate it’, 33).
