    Sperm quality parameters like volume and count decrease with shorter abstinence periods in both normozoospermic and oligozoospermic men. Optimal sperm analysis requires careful consideration of ejaculation frequency.

    Area of Science:

    • Reproductive Endocrinology
    • Andrology
    • Sperm Analysis

    Background:

    • Sperm analysis is crucial for male fertility assessment.
    • Abstinence duration significantly impacts semen parameters.
    • Understanding these variations is key for accurate diagnosis.

    Purpose of the Study:

    • To investigate the effect of varying abstinence intervals (1, 2, and 3 days) on sperm parameters.
    • To compare these effects in normozoospermic and oligozoospermic individuals.
    • To establish optimal recommendations for sperm sample collection.

    Main Methods:

    • Semen analysis was performed on two successive samples from 64 normozoospermic and 19 oligozoospermic men.
    • Samples were collected after a 3-day initial abstinence period, followed by 1-, 2-, and 3-day intervals.

  • Key parameters analyzed included sperm volume, sperm count, and sperm motility.

    • Main Results:

    • Sperm volume and count showed a declining trend in normozoospermic men with shorter abstinence intervals.
    • Oligozoospermic men also exhibited decreased sperm volume and count with reduced abstinence periods, with some exceptions.
    • Sperm motility showed variable changes across different abstinence intervals in normozoospermic men.

    Conclusions:

    • Shorter abstinence intervals (1-2 days) negatively affect sperm volume and count in both normozoospermic and oligozoospermic men.
    • The findings suggest that longer abstinence periods may be beneficial for obtaining representative semen analysis results.
    • Clinical recommendations for sperm sample collection should account for the impact of ejaculation frequency on semen quality.
