[Physiologic basis for the "attractiveness" of female rats for males]
Abstract:
Sexual behaviour of intact male rats was studied in tests with ovariectomized female rats and with those injected with sexual hormones. The data obtained support the hypothesis of the existence of central and peripheral mechanisms regulating the sexual behaviour of male rats. The treatment of castrated females with androgen resulted in males sniffing at them mor often, the copulatory behaviour being only observed in tests with females treated with estrogens in combination with progesterone.

Mate Choice
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
Natural Selection and Mating Preferences
The principle of natural selection posits that organisms better adapted to their environment are more likely to survive and reproduce. This principle is closely intertwined with mating preferences, a key aspect of sexual selection, which evolutionary psychologists believe is driven by instincts to propagate one's genes. Such instincts significantly influence mating behaviors and preferences between genders.
