Human semen prostaglandins do not affect sperm motility and migration

Area of Science:

• Reproductive biology
• Andrology
• Biochemistry

Background:

• Prostaglandins (PGs) and testosterone (T) are crucial for male reproductive function.
• Seminal plasma concentrations of these substances may reflect fertility status.

Purpose of the Study:

• To determine seminal plasma concentrations of Prostaglandin E2 (PGE2), Prostaglandin F2 alpha (PGF2 alpha), and testosterone (T) in men attending a fertility clinic.
• To investigate potential correlations between these seminal plasma components and sperm parameters, including count, motility, and migration, across different semen analysis groups.

Main Methods:

• Seminal plasma from 57 fertility patients was analyzed for PGE2, PGF2 alpha, and T concentrations.
• Patients were categorized into normospermic, oligozoospermic, asthenozoospermic, and azoospermic groups.
• Sperm migration was assessed using the Kremer capillary tube test with human cervical mucus.

Main Results:

• Mean seminal plasma concentrations were: PGE2 (3.44 ± 0.38 μg/ml), PGF2 alpha (138 ± 0.33 μg/ml), and T (429.54 ± 14.01 pg/ml).
• A statistically significant increase in PGE2 was found in the asthenozoospermic group compared to other groups.
• No significant correlations were observed between seminal PGs and T levels and sperm count, motility, or migration parameters.

Conclusions:

• Seminal PGE2 may be elevated in cases of poor sperm motility (asthenozoospermia).
• Seminal plasma concentrations of PGE2, PGF2 alpha, and T do not appear to correlate with sperm count, motility, or migration capacity in individual semen samples.
