PRP Therapy for Fertility Support in Women: How It Is Used and Studied
If you have been researching add-on options for your fertility journey, you may have come across PRP therapy for fertility support in women. At our Toronto clinic — FemRenew by Dr. Fay Weisberg, MD, FRCSC — we hear thoughtful questions about this approach almost every week. PRP, short for platelet-rich plasma, is an area of active research in reproductive medicine rather than an established, proven fertility treatment. We believe the most helpful thing we can do is explain what it is, what the science currently suggests, and where the honest uncertainties lie, so you can weigh it carefully together with your own physician.
This post is meant to inform a conversation, not to replace one. Fertility care is deeply personal, and the right path for one woman is not automatically right for another. Throughout, you will see us hedge our language on purpose. That is not us being vague — it reflects exactly where the evidence stands today.
What PRP Is and Why It Is Being Studied in Fertility Care
Platelet-rich plasma is made from your own blood. A small sample is drawn, then spun in a centrifuge to concentrate the platelets and the growth factors they carry. Those growth factors are the same signalling proteins your body uses during normal tissue repair. The concentrated plasma is then prepared for use in a specific area.
The interest in PRP for fertility comes from a simple question that researchers are still working to answer: if growth factors help tissue heal and regenerate elsewhere in the body, could a localized application support the uterine lining or ovarian tissue in select situations? It is a reasonable question, and several research groups around the world have explored it. But a reasonable question is not the same as a settled answer. Much of the published work so far involves small studies, varied techniques, and short follow-up. That is why most reproductive specialists, including us, describe PRP as developing and investigational rather than standard of care.
Two phrases come up often in this research. The first is thin endometrium — a uterine lining that does not thicken as much as hoped, which can matter for embryo implantation. The second is recurrent implantation failure, where good-quality embryos repeatedly do not implant despite reasonable conditions. PRP has been studied as a possible support in both contexts, and you will also see the term PRP ovarian rejuvenation used in research exploring whether platelet-rich plasma might influence ovarian tissue. We want to be clear: across all of these uses, the evidence is preliminary.
Who PRP May Be Discussed With
PRP is not something we would ever suggest as a first step or a shortcut. In the research literature, the women being studied have usually already been through a careful fertility workup and are working with a reproductive endocrinologist. The conversations tend to involve people who have faced specific, documented challenges — for example, a lining that has stayed thin across cycles despite standard measures, or repeated implantation failure that has been investigated thoroughly.
Because FemRenew was founded by a board-certified OB/GYN and we have a sister fertility practice, we are comfortable having frank, grounded discussions about where platelet rich plasma fertility research currently sits. We are equally comfortable saying when we do not think an add-on is appropriate. If you are at the very beginning of trying to conceive, the most evidence-based steps are usually a proper assessment and the established treatments your fertility team recommends — not an experimental adjunct.
It is also worth naming who PRP is not a fit for. Anyone hoping for a guarantee, anyone being asked to skip a real diagnostic workup, or anyone being sold PRP as a stand-alone cure for infertility should pause. Those are signs the conversation has drifted away from responsible care.
How PRP Therapy for Fertility Support in Women Is Being Studied
When we look at the research on PRP and fertility, a few honest points stand out, and we share them the same way every time.
First, the studies are early. Many are small, some lack control groups, and the techniques used to prepare and apply PRP differ from one study to the next. That variability makes it hard to draw firm, generalizable conclusions. Second, where researchers have reported encouraging signals — for instance, changes in endometrial thickness in certain participants — those findings are still being tested and replicated. Promising early data is genuinely promising, and it is also genuinely early. Both things are true at once.
Most importantly, and this is the line we never soften: PRP does not guarantee a pregnancy. No reputable provider can promise that it will help you conceive, and you should be cautious of anyone who does. We deliberately avoid quoting success percentages, because the current research does not support reliable, real-world figures for an individual woman. What we can do is help you read the evidence honestly and decide, with your physician, whether an investigational option fits your values, your medical picture, and your tolerance for uncertainty. That is what we mean when we say to weigh it carefully with your doctor.
If you do consider PRP, the appropriate setting is one where it complements a supervised fertility plan — not one where it replaces established care. The O-Shot, our in-clinic PRP application, is most often discussed in the context of comfort and intimate wellness; you can read more about our broader approach on our PRP and O-Shot page. Questions about the O-Shot and fertility are ones we hear regularly at our Toronto clinic, and we are glad to address them honestly — any fertility-specific conversation belongs within a coordinated plan alongside your reproductive specialist.
How FemRenew Can Help
At FemRenew in Toronto, our role is to give you clear, unhurried information and a realistic sense of where research-stage options fit. Because Dr. Weisberg is an OB/GYN and a member of the SOGC and NAMS, and because we have a sister fertility clinic, we can help you understand how something like PRP would — or would not — relate to a structured fertility plan. We will tell you plainly when we think the stronger move is to focus on established care first.
Your care with us begins with an OHIP-covered consultation. In Ontario, that means an initial medical conversation can take place under provincial coverage, so you can ask questions and understand your options before deciding anything. During that visit we listen to your history, talk through what you have already tried, and explain honestly what the evidence does and does not support. If a coordinated approach with our fertility colleagues makes sense, we can help connect those dots. To learn how we frame this area of care, you can also visit our PRP and infertility page.
What to Expect at a Visit
People are often relieved by how ordinary and calm the first visit feels. There is no pressure and no sales pitch. We start by understanding you — your goals, your history, and where you are in your journey. We answer questions directly, including the uncomfortable ones, and we are candid about uncertainty rather than papering over it.
If PRP comes up, we explain that it draws on a small sample of your own blood, how it is prepared, and why it remains investigational for fertility. We talk through what is realistic, what is unknown, and what the responsible next steps are. You leave with information you can take to your own physician, not a decision you felt rushed into. For many women, simply having a grounded, judgment-free conversation in Toronto is the most valuable part — whether or not PRP ends up being part of the plan.

Frequently Asked Questions
Is PRP a proven fertility treatment?
No. PRP for fertility-related uses such as thin endometrium and recurrent implantation failure is an active area of research, not an established or proven treatment. The published studies are mostly small and early, and findings are still being tested. We describe it as investigational and recommend deciding with your own physician.
Will PRP help me get pregnant?
We cannot say that it will. PRP does not guarantee a pregnancy, and no responsible provider should promise that it does. We intentionally do not quote success rates, because the current evidence does not support reliable individual figures. The honest answer is that it is being studied, and the decision should be weighed carefully with your physician.
What is PRP ovarian rejuvenation?
It is a term used in research exploring whether platelet-rich plasma might influence ovarian tissue. It is an area of investigation, not a standard or proven service, and it is not something we offer as a guaranteed solution. We are happy to discuss what the research does and does not currently show.
How is the O-Shot related to fertility?
The O-Shot is an in-clinic PRP application most often discussed in the context of intimate comfort and sexual wellness rather than fertility. Any fertility-focused use of PRP should sit within a coordinated plan alongside a reproductive specialist, not stand on its own.
Do I need a fertility workup first?
Yes. The appropriate place to even consider an investigational add-on is after a thorough assessment with a qualified provider, and within a supervised plan. If anyone offers PRP as a way to skip a real workup, we would treat that as a warning sign.
Does FemRenew offer this in Toronto?
We offer consultations where we explain, honestly and without pressure, where PRP research currently stands and how it might or might not relate to your situation. Because we have a sister fertility clinic, we can help coordinate care when appropriate. Your care begins with an OHIP-covered consultation.
