摘要
Ejaculates from boars (Landrace and Pietrain breeds) were examined by scanning electron microscopy and by Nomarski differential interference microscopy to detect aberrant and immature forms of spermatozoa. The findings were 85% normal mature spermatozoa and 15% abnormal forms. The latter included immature forms with a distal or proximal cytoplasmatic droplet, and several aberrant forms: (1) spermatozoa with folded tails at the Jensen ring or at the midpiece; (2) spermatozoa with folded heads along a longitudinal or transverse plane and with associated flagellar malformations; (3) spermatozoa with rounded heads; (4) spermatozoa with curved heads; (5) spermatozoa with elongated heads; (6) spermatozoa without tails; (7) spermatozoa with coiled tails; (8) spermatozoa with two tails; (9) spermatozoa with two or more heads and coiled tails; (10) spermatozoa with two heads and abnormal tails; and (11) short-tailed spermatozoa with or without flagellum. © 1990.
