Dr. Sasha Hakman - "When a woman can see her real hormone values across a cycle, not just a line on a stick, I can properly evaluate ovulatory patterns and possible pathologies like ovulatory infertility or short luteal phase. That helps women take action sooner to improve their reproductive outcomes, and that is what advocacy in women's health should look like." Dr. Roxanne Pero - " I encourage all fertility patients of mine to get an Inito monitor. They then share their daily charts with me and we adjust the plan accordingly based on that day's results. Having the ability to see and make quick adjustments is a game changer in the timing to conception for my patients! I love the ease of use and how accurate it is with low and high fertility ratings. Inito gives my patient an educational opportunity to learn what is going on with her body and her hormones in a real time, easily accessible and highly accurate - that no other device on the market can provide." Dr. Susan Nasab - "I recommend Inito because it empowers patients to monitor their cycles at home while generating clinically meaningful data for their fertility specialist. The full cycle calendar provides valuable insight into ovulation, cycle regularity, and hormonal trends, which is particularly important in cases of PCOS, ovulatory dysfunction, premature ovarian insufficiency, and early perimenopause. Having this detailed hormonal history allows us as REI physicians to make more informed decisions and personalize treatment more effectively." ## Tools - [Free Ovulation Calculator](https://inito.com/blog/ovulation-calculator): Predict your fertile window and ovulation day.
