In an average 28-day menstrual cycle, ovulation typically occurs around the 14th day of the cycle. According to Ayurvedic texts, Ritu Kaala is the Beeja Nishkraman Kaala and is therefore the most suitable period for conception. The symptoms of Ritu Kaala in a female are described as Ritumati Lakshana. The duration of Ritu Kaala is about 12-16 days after the cessation of menses, which closely corresponds to the time of ovulation. In this review study, detailed content and references are analysed from the Sushruta Samhita, Vagbhatta, and Charaka Samhita, as well as from relevant books and previous research articles. According to the Sushruta Samhita, the Ritumati Lakshana include Peena Prasanna Vadana (fat/fleshy/radiant / happy cheerful face), Praklinna Atma Mukha Dwijaam (moist body, face, gums/oral cavity), Nara Kaama (Increase in libido), Priya Katha (politeness in behaviour), Srasta Akshi, Kukshi Moordhajaam (flaccid/lax eyes, trunk, and head), Sphurati Bhuja, Kucha, Shroni, Naabhi, Uru, Jaghana, and Sphichaam (pulsation in or twitching of arms, breasts, pelvic region, umbilicus, thighs and hips), Harsha Autsukya (energetic/delight/happy and excitement). A systematic diagnostic methodology developed to evaluate these characteristics, incorporating biomarkers. The study demonstrates that the Rutumati Lakshanas described in Ayurvedic texts are appropriate for identifying the fertile period. Evaluating Ritu Kaal in relation to the fertile period of women can help determine the fertile window in infertile women. Ritukaal Ritumati Lakshan Estrogen Biomarker.
