Intra-individual changes in sperm parameters and total motile count with time among infertile men.

ABSTRACT:

Background

Paternal age association with sperm parameters has been previously studied, demonstrating a decrease in semen volume, sperm motility, and sperm morphology, but not in sperm concentration. However, scarce data exists on the individual intra-personal changes in semen parameters with time.

Study design

Retrospective cohort study.

Objective

To evaluate the changes in semen parameters and total motile count of infertile men over time.

Materials and methods

In this retrospective cohort study, infertile men without known risk factors for sperm quality deterioration and at least two semen analyses done > 3 months apart, between 2005 and 2021, were evaluated. Allocation to groups was according to time between first and last semen analyses - 3-12 months, 1-3 y
