  • Why You Should Use Opionato?

    Opionato is the first collaborative, multi-clinic, and multi-disciplinary fertility guidance service.

    Unbiased (No Conflict of Interest) Advice

    Opionato offers you unbiased and independent view through initial, ongoing, and/or second opinion advice before, during or after treatment that is only driven by evidence-based data and not by an individual fertility clinics' (often seen) one-size fits all treatment approaches or financial incentives. Opionato additionally does not have any affiliation with nor receive any funding from fertility clinics or pharmaceutical companies. And Opionato also does not receive referral fees from any of our experts or their clinics. Our focus is only on you and your best interests.

    Leading Fertility Experts

    Opionato gives you access to the very top US fertility specialists often unknown to us or unreachable to many due to a geographic barrier or clinic long-waiting times. We believe that everyone should have equal access to advice from the top authoritative voices in the field of fertility care.

    Evidence-Based Advice

    Opionato relies on latest scientific research and existing data-driven clinical research to advice you on the best path moving forward in your fertility journey when considering your condition, need, wishes, and lifestyle.

    Easy Access

    You can reach Opionato anytime from anywhere. And we work around your schedule to connect you with top U.S. fertility experts from the comfort and privacy of your home. We know you are busy and that you prefer privacy and confidentiality.

    No Waiting Time

    Opionato connects you with experts on the same day and provides you the service within 0-3 days. We know that timing is a critical factor for your optimal fertility care and peace of mind.

    Caring and Compasionate Service

    Opionato's team has experienced first-hand the confusion and the lack of clarity, transparency, and trust during our own fertility journeys. We have created Opionato as a service we wished we had for ourselves: respectful, genuine, compassionate, caring, and credible.

    Affordable Service

    Opionato service is affordable and represents a small add-on expense to the overall treatment cost-one that can ultimately save you a lot of stress, time, and money down the line by having you avoid additional, unnecessary, and inefficient fertility treatments. Our goal is to empower you with the right information so you can make wise and informed decisions regarding your fertility options that will optimize your chance of having a baby when and how you prefer.

    One Place Hub for All Your Fertility Needs

    Compared to fertility clinics who often do not have all fertility expertise in-house, Opionato works with a full-stack team of fertility experts that includes reproductive endocrinologists, embryologists, reproductive genetic counselors, reproductive emotional counselors, and fertility nurse practitioners. We know well that optimal fertility care requires a multidisciplinary approach spanning medical, genetic, embryology, and emotional components.

    Serving All Fertility Needs

    Opionato helps you have a baby whether you are a heterosexual or LGBT individual or couple struggling to conceive naturally, are facing a recent infertility diagnosis, are undergoing fertility treatment, or perhaps are interested in pursuing egg freezing. We know that each fertility journey is different and requires a personalized, timely, and caring approach.
