Estudio de la selección espermática en el tracto genital de la hembra basado en la morfometría del espermatozoide porcino

Abstract

In the Faculty of Veterinary Medicine, University of Murcia, Spain, the morphometry of the spermatozoa was evaluated in the ebbs of bristles after artificial insemination implementation, having as factors studies employees pigs (5 animals), type of insemination (cervical and post-cervical), and the time when the waters recede (0-15, 16-30 and 31-60 minutes) was collected. In addition, samples from washes of different sections of the female reproductive tract (uterus, fallopian tubes and utero-tubal, left and right side) obtained after surgery sows artificially inseminated 24 hours before analyzed, so that the samples were distributed under a completely randomized design with unequal number of repetitions: The results determined that sperm morphometry statistical changes suffered as a result of the players tested, by type of insemination (post-cervical and cervical), highly significant differences were found top answers sperm collected after post-cervical insemination, equally influenced collection time because morphometric measurements are reduced with respect to the original dose, with the following results of the sperm heads of fresh semen and collected between 31 and 60 minutes, 9.18 and 8.98 microns length, width 4.42 vs 4.27 microns, 34.53 to 32.86 .mu.m area and perimeter ² 24.65 to 24.13 microns, respectively. Older queue lengths were in the original dose (46.84 microns), unlike the uterine lavage collected (45.65 microns).
