Comparison of Sexual Behavior Patterns in Small Laboratory Animals
Experimental Animals, 1993 It is known that in the reproductive systems, aged-related changes are prominent. Similarly, in normal nonhuman primates and other mammals such as rats, various sexual activities of male and female decline with aging. The purpose of the present study was to clarify the pattern of sexual behavior in matured mice, voles, Syrian hamsters, rats, guinea ...

Sexually dimorphic nuclei in the spinal cord control male sexual functions
Frontiers in Neuroscience, 2014 Lower spinal cord injuries frequently cause sexual dysfunction in men, including erectile dysfunction and an ejaculation disorder. This indicates that the important neural centers for male sexual function are located within the lower spinal cord. It is

Estrous behavior in dairy cows: identification of underlying mechanisms and gene functions [PDF]
, 2010 Selection in dairy cattle for a higher milk yield has coincided with declined fertility. One of the factors is reduced expression of estrous behavior. Changes in systems that regulate the estrous behavior could be manifested by altered gene expression ...

MORPHOLOGY, REPRODUCTION, SEASONAL ACTIVITY AND HABITAT USE OF A NORTHERN POPULATION OF THE SMOOTH GREENSNAKE (OPHEODRYS VERNALIS) [PDF]
, 2020 The Smooth Greensnake (Opheodrys vernalis) is a small, slender, oviparous, colubrid snake that is widely distributed in North America. Nonetheless, there have been few studies on this species, and little is known about Canadian populations. The objective

Effects of chronic tamoxifen treatment in female rat sexual behaviour
Heliyon, 2022 The medial preoptic (MPN) and the ventromedial hypothalamic nuclei (VMN) modulate the estrogen receptor (ER)-dependent female sexual behavior, a response that is inhibited by tamoxifen (TAM), a modulator of the steroid receptor activation.

Sex differences in the pituitary TGFβ1 system: the role of TGFβ1 in prolactinoma development [PDF]
, 2019 Prolactinomas are the most frequent functioning pituitary adenomas, and sex differences in tumor size, behavior and incidence have been described. These differences have been associated with earlier diagnosis in woman, as well as with serum estradiol ...

Female sexual behavior in mice is controlled by kisspeptin neurons
Nature Communications, 2018 Mate preference and copulatory behavior in female rodents are coordinated with the ovulation cycles of the animal. This study shows that hypothalamic kisspeptin neurons control both mate choice and copulation, and therefore, that sexual behavior and ...

The Animal Sexes as Historical Explanatory Kinds [PDF]
, 2020 Though biologists identify individuals as ‘male’ or ‘female’ across a broad range of animal species, the particular traits exhibited by males and females can vary tremendously.
