Main comments:
Dear Author, congratulations on your successful study. Overall, the manuscript is well written, and the results are very and convincing, but several minor corrections need to be made. My suggestions are presented in the appendix.

Reviewer 2 Report
Dear authors, I enclose my comments:
Title
The title should be shortened by indicating method, sample and objective only. Recommendation.
General comments
- The term "sex" (biological) and not "gender" (cultural) should be used.
Abstract
The abstract adequately summarises the research, including the main findings of the results and the conclusions. However, it does not specify clearly and concretely the objective and methodology used.
Keywords:
Changing gender.
Introduction
The general idea of the research is presented with an adequate and up-to-date theoretical framework.
Materials and Methods
All procedures are correctly defined.
Reference authors should be included for each test.
Results
They are adequately presented.
Check the different tables. The data F, p & ES values, I would advise to place them by columns for a correct reading and visualisation (more agile).
This symbol is not defined or it is a misprint: ¶
Discussion
It is well contrasted and justified with the existing literature.
Conclusions
They are clear.
Limitation
Reference should be made to the different types of sand (grammage, washed sand or not, wet or not, etc.). This is undoubtedly a limiting factor and can cause bias. It should therefore be reflected as an important aspect.
References
Journals should be in abbreviated format.
Check year and page format.
Check spacing between words. Double spaces or none at all.
Best regards.
