Effect of platelet-rich plasma on patients with normal endometrium undergoing in vitro fertilization at a reproductive center in Mexico.

OBJECTIVE

To compare the effect of platelet-rich plas-ma (PRP) on pregnancy rates versus the placebo group in patients with normal endometrium undergoing advanced assisted reproduction treatments.

METHODS

Randomized, double-blind clinical trial that compared the use of PRP versus placebo (sterile saline solution) in patients undergoing endometrial preparation for frozen embryo transfer after in vitro fertilization. A total sample size of 52 patients was determined, and the pa-tients were randomized into two groups (n=26 per group). The groups were treated with either PRP or a placebo at the appropriate time. The impact on pregnancy rates and endometrial thickness was analyzed subsequently. Groups were compared using t-tests, U-tests, or chi-squared tests. A p-value<0.05 was considered statistically significant.

RESULTS

The study analyzed an intervention group (PRP) and a control group (placebo). The overall pregnan-cy rate during the study period (n=52) was 38.4%, and the live birth rate was 33.3%. The pregnancy rate was 26.9% in the intervention group and 46.2% in the control group, with no significant difference between the groups (p=0.15). Similarly, no differences were found in endome-trial thickness and endometrial morphology between the groups analyzed (p>0.05).

CONCLUSION

There are no differences in favor of the PRP or control group in terms of achieving pregnancy, so the use of PRP in normal endometrium does not currently show advantages as an adjuvant to what is already used in women without other factors that alter endometrial re-ceptivity.
