Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It,s a retrospective case-control pilot study is to be carried out. Twenty patients will be included in the study for each branch (a total of 60). The study population will be patients whose partners have a diagnosis of an altered vaginal microbiome with (Cases, n = 20) or without (Controls, n = 20) persistence to drug treatment. Since a normal reference seminal microbiome has not been described, we will include a control group that will consist of sperm donors (n = 20) who are considered fertile potential without reproductive problems.

The main objective of the project is to identify the interaction of the vaginal and seminal microbiome patterns in couples in which the vaginal pattern is altered and is persistent to drug treatment.

semen donors

The semen donors included in the present work will be men between 18 and 35 years old who are included in the donation program of Instituto Bernabeu after having passed a series of physical, psychological, analytical, genetic and serological evaluations and are considered suitable for donation as established by Royal Decree-Law 9/2014. Likewise, donors are subjected to a series of seminal quality evaluations and seminal freeze-thaw tests in order to guarantee their fertile potential. In this way, the donors who are part of the Instituto Bernabeu donation program also comply with current legal regulations with a strict evaluation to be considered the gold standard of potentially fertile semen. In addition, it will be necessary for them to provide a signed informed consent accepting their participation in the study.
