研究概览

简要总结

The goal of this study is to learn about the impact of abstinence periods on sperm quality in healthy males 20-45 years of age with no significant comorbidities who are able to produce a semen sample via masturbation. The main question it aims to answer is:

• Do shorter abstinence periods result in improved semen quality?

Participants will provide semen samples for analysis following abstinence periods of 7 days, 5 days, 2 days, 1 day, and 3 hours.

详细描述

Participant Duration: Total length of time on study per subject is 14 days (including 5 days of visit required for sample production). Subjects do not need to complete the visits in order but need to document abstinence period prior to sample production. No follow up will be needed after the study.

Primary Objective: The primary objective is to examine the differences in semen analysis parameters after varying abstinence periods (7 days, 5 days, 2 days, 1 day, 3 hours).

Secondary Objectives: The secondary objective(s) is to assess changes in sperm DNA fragmentation after varying abstinence periods (7 days, 5 days, 2 days, 1 day, 3 hours).

结局指标

主要结局

Change in semen analysis parameters based on different abstinence periods: sperm concentration

时间窗: 7 days, 5 days, 2 days, 1 day, 3 hours

The primary objective is to examine the differences in semen analysis parameters (sperm concentration measured in million sperm/mL) after varying abstinence periods (7 days, 5 days, 2 days, 1 day, 3 hours).

Change in semen analysis parameters based on different abstinence periods: volume

时间窗: 7 days, 5 days, 2 days, 1 day, 3 hours

The primary objective is to examine the differences in semen analysis parameters (volume in mL) after varying abstinence periods (7 days, 5 days, 2 days, 1 day, 3 hours).

Change in semen analysis parameters based on different abstinence periods: motility

时间窗: 7 days, 5 days, 2 days, 1 day, 3 hours

The primary objective is to examine the differences in semen analysis parameters (motility measured as a percentage) after varying abstinence periods (7 days, 5 days, 2 days, 1 day, 3 hours).

次要结局

  • Change in sperm DNA fragmentation based on different abstinence periods(7 days, 5 days, 2 days, 1 day, 3 hours)
