    Spermatozoa may transport bacteria from seminal fluid into the female reproductive tract. This migration through cervical mucus, observed during the ovulatory phase, could contribute to infections like salpingo-oophoritis.

    Area of Science:

    • Reproductive biology
    • Microbiology
    • Gynecology

    Background:

    • Cervical mucus plays a role in sperm transport and may harbor microorganisms.
    • The interaction between spermatozoa, cervical mucus, and bacteria is not fully understood.

    Purpose of the Study:

    • To investigate the role of spermatozoa in the migration of microorganisms within cervical mucus.
    • To determine if spermatozoa act as a vehicle for bacterial transport into the female reproductive tract.

    Main Methods:

    • Observing microbial migration within ovulatory-phase cervical mucus columns alongside spermatozoa.
    • Culturing microorganisms from the distal end of mucus columns after sperm migration.
    • Introducing exogenous bacteria to seminal fluid and observing their movement in mucus.

    Main Results:

    • Microorganisms were observed migrating within cervical mucus concurrently with spermatozoa.
    • Identical aerobic and anaerobic microbial isolates were recovered from seminal fluid and the distal mucus column.
    • Exogenous bacteria introduced to seminal fluid migrated to the top of the mucus column.
    • Bacteria did not migrate through mucus in the absence of spermatozoa.

    Conclusions:

    • Spermatozoa likely serve as a vehicle for transporting bacteria from seminal fluid into the female reproductive tract.
    • This spermatozoal-mediated bacterial transport may contribute to the development of upper genital tract infections, such as salpingo-oophoritis.
