Rutumati Lakshanas-Estrus Signaling In Humans

Abstract

The word 'peena' denotes fat/round/fleshy face and the word 'prasanna' denotes happy/cheerful face. During rutu kala the women's face becomes attractive according to Ayurveda. Female facial attractiveness increases during the fertile phase of menstrual cycle. Female's faces become most attractive to males AbstractRutu is the period of ovulation in a female and 'Rutu kala' denotes the peak fertility period in women. 'Rutumati' is the woman who is in peak fertility period (from the 4 th day of the menstrual cycle to 15 th day of the menstrual cycle in healthy women). According to 'Sushruta samhita', peena vadana (fat/fleshy/round face), prasanna vadana (bright /cheerful/attractive face), praklinna atma, mukha, dwijaam (humid /moist body, face, gums/oral cavity), nara kaama (interested in men), priya katha (interested in listening stories), srasta akshi, kukshi moordhajaam (flaccid/lax eyes, trunk and head), sphurati bhuja, kucha, shroni, naabhi, uru, jaghana and sphichaam (shining/quivering/expansion of shoulders, breasts, hips & loins, umbilicus/ abdomen, thighs, vulva/mons veneris and buttocks), harsha (pleasure/delighted) and autsukya (eagerness/desire/excitement) are considered as Rutumati lakshana's. These Rutumati lakshana's are getting proved by latest research and there is a striking similarity found between Rutumati lakshana's and functions of estrogen hormone/ human estrus/follicular phase/peak fertility period in women. Women have been thought to possess no distinctive sexuality during the fertile phase of their menstrual cycle. Abundant evidence now indicates that they do. Ancient Ayurvedic sages were able to detect ovulation in females by observing the various physiological and behavioral cues which occur during peak fertility. This supports the view that human ovulation is not concealed.
