Long-term evaluation of sperm parameters after coronavirus disease 2019 messenger ribonucleic acid vaccination.

ABSTRACT:

Objective

To determine whether the COVID-19 mRNA vaccines can negatively impact the semen parameters of young healthy men in the long-term.

Design

We conducted semen analyses on 12 men before, 3 and 9 months after achieving fully vaccinated status. Individuals who admitted a history of infertility or previous azoospermia were excluded from study participation.

Subjects

Healthy male volunteers between the ages of 18-50 years old were recruited between September 2021 - March 2022.

Main outcome measures

Semen analyses were performed and evaluated volume, sperm concentration, total motility, and total motile sperm count (TMSC). The primary outcome was median change in the TMSC at baseline, 3 months, and at least 9 months following vaccination.
