Assessing the Effect of Abstinence Period on Semen Parameters
Study Details
Study Description
Brief Summary
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.

Detailed Description
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).

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Healthy Volunteers Healthy males with no significant comorbidities, aged 20-45 years who are able to produce a semen sample by masturbation. |
Other: Abstinence followed by semen sample collection.
Abstinence is the intervention. Semen samples will be collected after abstinence periods.

Outcome Measures
Primary Outcome Measures
- Change in semen analysis parameters based on different abstinence periods: volume [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: sperm concentration [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: motility [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).
Secondary Outcome Measures
- Change in sperm DNA fragmentation based on different abstinence periods [7 days, 5 days, 2 days, 1 day, 3 hours]
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).
