Alterations in feeding and sexual behaviour during reproductive cycle in female rats.

ABSTRACT

Alterations in feeding and sexual behaviour were studied in adult female rats. During estrous phase there was decrease in food intake and increased sexual behaviour, as manifested by increased lordosis quotient. During met-and diestrous phases, increase in food intake and depressed sexual behaviour were observed, indicating inverse relationship between these two behaviours. Multisensory hypothalamic neurons may explain interactions among regulatory systems.
