The possession of permanent, adipose breasts in women is a uniquely human trait that develops during puberty, well in advance of the first pregnancy. The adaptive role and developmental pattern of this breast morphology, unusual among primates, remains an unresolved conundrum. The evolutionary origins of this trait have been the focus of many hypotheses, which variously suggest that breasts are a product of sexual selection or of natural selection due to their putative role in assisting in…

TLDR
It is proposed that breasts and buttocks evolved to signal the female's nutritional state to males, in the context of facilitating female choice of mate, and that humans stand out against a general background of sexual selection wherein many animals exhibit male ornaments to attract females.

Possible ways in which the adaptive significance of human breasts can be determined in contemporary populations are outlined.
On the Adaptive Significance of the Female Breast
The evolution of the rounded or protuding breast in the human female has recently been reassessed by Crook (1972). Opinions differ whether the breast functions as a mimic device to arouse sexual

TLDR
There is no clear evidence yet that estrogen replacement therapy can prevent or reverse pelvic floor dysfunction, and it is hard to postulate mechanisms for HRT that might reverse established uterovaginal prolapse.
A hypothesis for the origin and evolution of menopause.
TLDR
Results of a mathematical model are presented which show that reproductive senescence can be advantageous even when maximum potential lifespan is only 50 years, if the premature cessation of reproduction allows females to moderately increase the survival and fertility of their existing subadult offspring.

Loss of Oestrus and Concealed Ovulation in Human Evolution
TLDR
Analysis of the sexual behaviour of nonhuman primates and humans indicates that constant receptivity is not unique to humans and that human sexual behaviour is not independent of the phases of the menstrual cycle, assuming the existence of direct selection pressures on sexual behaviour in the Plio/Pleistocene evolution of the Homininae seems unjustified.

Like that of many other mammals, our rate of reproduction is related to the carrying capacity of our habitat, and throughout our history low lifetime fertility has been advantageous. The most
