Female sex drive is also known under the name female libido. Libido is viewed as a woman's general sexual drive or appetite for sexual activity. In a study by Fisher HE under the title "Romantic love: a mammalian brain system for mate choice" it has been noted that libido is equally influenced and affected by three factors:
the social factor
the biological factor
the psychological factor
According to some studies, based on the menstrual cycle and ovulation the female libido changes during the month. Ovulation is the process of releasing an egg from a female's ovaries. This action lasts between 24 and 48 hours, the egg travels down the fallopian tube where it may be fertilized. If fertilization does not occur, a period might be expected after approximately fourteen days. During ovulation, estrogen and testosterone levels are increased, which initiates a rise in libido.
