Triptonide is a reversible non-hormonal male contraceptive agent in mice and non-human primates
Nature Communications, 2021 No male contraceptive pills are currently available. Here, the authors use triptonide, a compound derived from a Chinese plant, to deform sperm so that they cannot move properly, thereby causing reversible infertility in male mice and monkeys.

Strong gender differences in reproductive success variance, and the times to the most recent common ancestors [PDF]
Journal of Theoretical Biology 310, 43-54 (2012), 2012 The Time To the Most Recent Common Ancestor (TMRCA) based on human mitochondrial DNA (mtDNA) is estimated to be twice that based on the non-recombining part of the Y chromosome (NRY). These TMRCAs have special demographic implications because mtDNA is transmitted only from mother to child, and NRY from father to son.

Why Y chromosome is shorter and women live longer? [PDF]
Eur. Phys. J. B 65, 149-153 (2008), 2008 We have used the Penna ageing model to analyze how the differences in evolution of sex chromosomes depend on the strategy of reproduction. In panmictic populations, when females (XX) can freely choose the male partner (XY) for reproduction from the whole population, the Y chromosome accumulates defects and eventually the only information it brings is a

Excitatory and inhibitory interactions affect the balance of chorus activity and energy efficiency in the aggregation of male frogs: Theoretical study using a hybrid dynamical model [PDF]
arXiv, 2021 We theoretically study the role of excitatory and inhibitory interactions in the aggregations of male frogs. In most frogs, males produce sounds to attract conspecific females, which activates the calling behavior of other males and results in collective choruses.
