Objective: To investigate the presence of surfactant protein-A (SP-A); molecular weight 34 kDa and surfactant protein-D (SP-D); and molecular weight 43 kDa in human spermatozoa.
Design: Prospective, research study.
Setting: Two universities in Turkey.
Patient(s): Semen specimens (n = 10) were obtained from normozoospermic donors.
Intervention(S): Human sperm were exposed to an anti-human SP-A polyclonal antibody, and monoclonal antibody, to human SP-D protein.
Main Outcome Measure(s): Presence of SP-A and SP-D proteins in human beings.
Result(s): Indirect immunofluorescence assays of human sperm indicated the presence of SP-A in the mid piece, the tail, and sometimes at the equatorial region of spermatozoa. A brilliant green light detected SP-D in the tails and acrosome of some sperm. The anti-SP-A antibody detected a single band corresponding to the molecular weight values of 34 kDa in spermatozoa, whereas no band was observed in the negative control. The anti-SP-D antibody showed the expected band at 43 kDa in spermatozoa.
Conclusion(S): This is the first report and a novel finding of the presence of surfactant glycoproteins on human spermatozoa. (Fertil Steril (R) 2008;90:1904-9. (C)2008 by American Society for Reproductive Medicine.)
