If you’ve started reading about PRP, it’s likely your fertility journey hasn’t been simple. Maybe your IVF cycles haven’t worked as hoped. Maybe embryo transfers were cancelled because your lining didn’t develop well. Maybe you’ve heard this mentioned as a “next step” and you’re trying to understand whether it’s right for you.
We’d like to explain PRP clearly and honestly — what it is, where it may help, and where expectations need to be realistic.
What is PRP?
PRP stands for Platelet-Rich Plasma.
It’s prepared from a small sample of your own blood. That blood is processed to concentrate platelets — cells that naturally release substances involved in:
- Tissue repair
- Formation of new blood vessels
- Cellular healing and regeneration
These substances, known as growth factors, act like signals that help tissues respond and recover. PRP has been used in other areas of medicine for years, including orthopaedics and wound care. In fertility treatment, its role is still being studied.
Why is PRP Used in Fertility Care?
For an embryo to implant successfully, the uterine lining must:
- Reach adequate thickness
- Have good blood supply
- Be biologically receptive to implantation
PRP is being explored because its growth factors may help support tissue response and blood vessel development in the endometrium.
Research is ongoing. Some patients appear to benefit, while others do not. It is not a universal solution.
PRP For a Thin Uterine Lining
One of the main situations where PRP is considered is when the lining remains thin despite standard treatments such as oestrogen therapy.
Why Lining Thickness Matters
A poorly developing lining can be associated with lower implantation rates. However, thickness alone does not determine success – lining quality and embryo health are equally important.
What Studies Show
Some clinical studies have reported that in selected patients:
- PRP placed into the uterus may increase lining thickness
- Some patients subsequently achieve pregnancy
However:
- Many studies are small
- Not all are randomised or high-quality trials
- Results are not consistent for everyone
For this reason, PRP for thin lining is seen as a developing option, not routine treatment.
PRP For Repeated Implantation Failure
When good-quality embryos do not implant, it can be extremely difficult. Repeated implantation failure can involve multiple factors:
- Embryo chromosomal abnormalities
- Uterine conditions
- Hormonal balance
- Immune factors
- Sometimes, chance
PRP has been studied as a way to improve the uterine environment in these cases. Some research suggests it may support blood flow and influence implantation-related signals. Still, it does not address embryo genetic issues, which remain a major cause of failed implantation.
PRP may be considered in selected cases, particularly when there is concern about lining development or uterine receptivity.
PRP and Ovarian Function
PRP has also been discussed for low ovarian reserve or poor ovarian response. This involves injecting PRP into the ovaries.
At present:
- Research is at an early stage
- Evidence is limited
- This approach is considered experimental in most fertility settings
Patients should approach this option with careful counseling.
Is PRP Safe?
Because PRP uses your own blood, allergic reactions are unlikely, as long as it is performed in an appropriate medical setting.
Long-term fertility data are still evolving.
What PRP Can and Cannot Do
PRP is not:
- A guarantee of pregnancy
- A treatment for embryo chromosomal abnormalities
- A substitute for a full fertility evaluation
It may be considered when:
- The lining repeatedly does not develop adequately
- Standard approaches have not been successful
- There is a reasonable medical basis to focus on the uterine environment
PRP works, if at all, as part of a broader, individualised treatment plan.
Why Individual Assessment Matters
After repeated disappointments, it’s completely understandable to want to try everything available. However, additional treatments should always be chosen for a clear medical reason.
At CRP Clinic, we use add-on treatments only when they are appropriate for the individual, not simply because they are available.
A Final Note From Our Team
Needing more detailed investigations or advanced treatment does not mean you’ve done something wrong. Recurrent implantation difficulties and lining problems are complex medical issues, and they deserve thoughtful, specialist care.
PRP is one of several developing tools in fertility medicine. For some patients, it may play a role. The most important part of care, however, is a plan built around your specific history, based on current evidence and delivered with support throughout the process.
You do not have to make these decisions on your own.
