Infertility is an increasingly common issue, affecting over 22% of married women who struggle to conceive or carry a pregnancy to term. While physical causes like anovulation, tubal damage, or endometriosis account for many cases, hormonal imbalances are often overlooked yet highly treatable contributors to infertility. The ZRT Fertility Profile offers a comprehensive and convenient way to evaluate hormone levels that are essential for conception and pregnancy maintenance. By testing markers like FSH, LH, estradiol, progesterone, testosterone, thyroid hormones, and cortisol, this profile helps identify conditions such as ovarian insufficiency, luteal phase deficiency, PCOS, thyroid dysfunction, and stress-related hormonal disruption. Samples can be collected easily at home through fingerstick blood and saliva on specific days of the menstrual cycle, ensuring accurate and timely results. Early identification of hormonal imbalances empowers women to take corrective action—often through simple lifestyle changes or targeted therapies—before turning to more invasive fertility treatments. Whether you’ve been trying to conceive without success, experienced recurrent miscarriages, or are planning ahead for pregnancy, ZRT’s Fertility Profile provides critical insights to help you and your healthcare provider take proactive steps toward reproductive health and success.
