Testes size, testosterone production and reproductive behaviour in a natural mammalian mating system [PDF]
, 2011 1. Testosterone (T) is a key mediator in the expression of numerous morphological and behavioural traits in mammals, but the factors underlying individual variation in circulating T levels are poorly understood. 2.

Sperm morphology and the evolution of intracellular sperm-egg interactions [PDF]
, 2018 Sperm morphology is incredibly diverse, even among closely related species, yet the coevolution between males and females of fertilization recognition systems is necessary for successful karyogamy (male and female pronuclear fusion). In most species, the

Patch clamp studies of human sperm under physiological ionic conditions reveal three functionally and pharmacologically distinct cation channels [PDF]
, 2014 Whilst fertilizing capacity depends upon a K+ conductance G? that allows the spermatozoon membrane potential Vm to be held at a negative value, the characteristics of this conductance in human sperm are virtually unknown.

Sperm production, quality, and post-copulatory performance in Australian Estrildid finches [PDF]
, 2019 Birds are obligately polyspermatic, and require multiple sperm to fuse with the ovum for successful fertilisation and embryonic development. Some optimal number of functionally competent sperm need to survive and traverse the oviduct to reach the ovum ...

Lactation, Childrearing, and Gender Justice
Journal of Applied Philosophy, EarlyView.ABSTRACT In this article, I discuss the significance of early infant feeding choices for the goal of gender justice. Focusing on human lactation practices, I identify Exclusive Gestational Nursing (EGN) as the norm in advanced industrial societies, which creates the expectation and permission for gestators, and only gestators, to nurse children, and ...

Beyond Substitution—An Antipositionalist's Guide to Subtraction—
Philosophy and Phenomenological Research, EarlyView.ABSTRACT Existing accounts of relations do not properly account for variably polyadic relations: they fail to capture the relationship between completions of the same relation by different numbers of relata. This paper develops a fully general account of such relations by adding an operation of subtraction to the antipositionalist theory of relations ...

Studies on the sperm reservoir of the pig oviduct [PDF]
, 2003 During sperm transport in the female pig a proportion of spermatozoa are arrested, often for 24 h or more, in a particular segment of the utero-tubal junction (UTJ) and the adjacent tubal isthmus, where a sperm reservoir (SR) is built up.

An update on the potential for male contraception : emerging options [PDF]
, 2013 The human population continues to grow and is estimated to rise to 10.1 billion by the end of the century. Therefore, there is still an unmet need for safe and highly effective contraceptive options for both men and women.
