What does the CYP11A1 (Sex Hormones) gene do?

CYP11A1 provides instructions for making an enzyme that starts steroid hormone production by converting cholesterol into pregnenolone. Pregnenolone is the “building block” used to create many hormones, including estrogen, progesterone, testosterone, DHEA, cortisol, and aldosterone. In simple terms: CYP11A1 helps your body begin the process of making key hormones that affect reproduction, stress response, and overall endocrine balance.

Why is the CYP11A1 (Sex Hormones) gene important?

Because CYP11A1 sits at the beginning of steroid hormone synthesis, genetic differences in this gene may influence downstream hormone levels and hormone-related health tendencies. Research has linked certain CYP11A1 variants with reproductive health conditions such as PCOS and recurrent pregnancy loss, and with hormone-related cancer risks in specific contexts (including reported associations with breast and endometrial cancer risk markers). Your DNA results don’t diagnose disease, but they can highlight where you may benefit from more proactive monitoring and personalized lifestyle support.

What can I do based on my CYP11A1 (Sex Hormones) results?

Based on your CYP11A1 (Sex Hormones) results, you’ll receive 5 personalized recommendations tailored to your genotype. These include lifestyle and supplement guidance you can use to support hormone pathways and reproductive health goals. Your report may suggest areas to focus on such as weight, sleep, stress physiology, and nutrition patterns that influence hormone balance, along with targeted supplement options that support steroid hormone production or related metabolic pathways—always framed as personalized, actionable next steps.

Which CYP11A1 variants are linked to PCOS and reproductive health risk?

Multiple CYP11A1 variants have been studied in relation to reproductive health. In published research, rs11632698 (G allele) and rs4077582 (T allele) have been associated with increased risk of PCOS and recurrent pregnancy loss in certain populations. Additional variants reported in association with increased PCOS risk include rs4887139 (A allele), rs4886595 (C allele), and rs6495096 (G allele). Your report evaluates 9 SNPs in CYP11A1 and explains how your specific combination of variants may relate to researched reproductive health signals, along with personalized, practical recommendations you can apply.

What do CYP11A1 genetic test results mean for hormone-related cancer risk?

CYP11A1 influences the earliest step of steroid hormone production, which is why it has been investigated in hormone-sensitive conditions. Research has reported that rs2279357 (T allele) is associated with increased breast cancer risk in women in some studies, while also being linked to decreased risk of late-onset hypogonadism in certain male cohorts. Other variants—rs4555110 (A allele), rs3825944 (A allele), and rs7173655 (C allele)—have been associated with increased endometrial cancer risk in published research. Your DNA report helps you understand whether you carry these studied variants and provides personalized lifestyle and supplement recommendations to support overall hormone health, while encouraging appropriate screening conversations with a clinician when relevant.

Understanding Your CYP11A1 (Sex Hormones) Variants: A DNA Gene Report

Do you ever wonder why your hormone balance feels “off,” why cycles or fertility goals can be harder than expected, or why certain hormone-related health risks seem to run in your family? The CYP11A1 (Sex Hormones) gene helps kick-start the body’s steroid hormone production—supporting pathways that influence estrogen, progesterone, testosterone, DHEA, and more. Understanding your unique CYP11A1 variants can help you connect the dots between your biology and your reproductive, hormone, and long-term health—so you can make more informed, personalized choices.

Key Report Highlights

This CYP11A1 (Sex Hormones) Gene Report analyzes 9 clinically relevant genetic variants (SNPs) and translates your results into 5 personalized recommendations. CYP11A1 encodes a key enzyme that converts cholesterol into pregnenolone—the foundational “starter” molecule from which all steroid hormones are made. Because this step sits at the top of the hormone-production pathway, CYP11A1 can influence multiple downstream systems at once, including reproductive function, pregnancy-related processes, and hormone-sensitive health outcomes.

Personalized, Actionable Recommendations

Your results are interpreted based on your specific CYP11A1 (Sex Hormones) genotype, then paired with personalized lifestyle and supplement recommendations designed to be practical and actionable. Depending on your variant pattern and associated research signals, your plan may include guidance such as targeted nutrition and lifestyle strategies that support healthy steroid hormone production and metabolic balance, or supplement suggestions that align with hormone pathway support (for example, micronutrients commonly involved in steroidogenesis and ovarian/testicular function). Your report focuses on DNA-informed personalization—so you can prioritize actions that best fit your biology.

User-Friendly Format and Trust

With actionable and easy-to-understand recommendations, the report is designed for seamless integration into your daily life. Its user-friendly format ensures accessibility, making complex genetic data understandable and practical for users at all levels of familiarity with genetic information.

The report is rooted in accuracy and reliability, backed by comprehensive scientific research from reputable sources. It has garnered the trust of over 150,000 users and 1,000+ healthcare professionals. Furthermore, the report complies with HIPAA and GDPR, ensuring your privacy and security are prioritized.

Honestly, I didn’t expect it to be so accurate for my hormone situation.

I showed this to my doctor, and he appreciated the specific guidance about things like BPA and phthalates. He said it helped him understand my hormone issues better. We’re now working on a targeted plan for my long-term health. Felt like this really added value to my usual care.

The CYP11A1 (Sex Hormones) report connected dots I had been missing for years, low libido, irregular cycles, and that wired but tired feeling. It explained how CYP11A1 sits upstream of pregnenolone and downstream hormones, then gave practical steps I could actually follow. I swapped to glass for leftovers, cut scented products to reduce phthalates, and started actively avoiding BPA and organochlorine pesticide exposure. After about six weeks, my sleep and mid cycle mood felt steadier. I liked that it focused on endocrine disruptors, not just supplements.

After getting my cyp11a1 results, I brought them to my naturopath and she was so impressed with how detailed and actionable everything was. We actually adjusted my supplement plan a little, especially with pregnenolone. This gave more direction and has been helpful for my ongoing hormone balancing.
