When it comes to sex, a female rat knows how to avoid a communication breakdown. To announce her sexual readiness, she will automatically arch her back, deflect her tail and stand rigid to allow an aroused male to mount. Now, Rockefeller University researchers have figured out the precise chemical and physical mechanism in a group of brain cells that controls this swayback posture, a reflex called lordosis that signals one of life’s most complex yet primitive instincts—the need for sex

Estradiol (E2) modulates affective and socio-sexual behavior of female rodents. E2's functional effects may involve actions through alpha and beta isoforms of estrogen receptor (ERs). The importance of E2's actions at these isoforms for anxiety (open field, elevated plus maze), depression (forced swim test), and sexual behavior (lordosis) was investigated using an antisense oligonucleotide (AS-ODN) strategy.ERbeta and ERalpha may be required for E2's modulation of affective and sexual behavior, respectively.
