| By understanding the hormonal action behind the induction of spermiation in Leptodactylus ocellatus can help in the collection of semen for artificial insemination and cryopreservation. The experiments were conducted at the Experimental Frog Farm of the Federal University of Viçosa. Seven L. ocellatus males with the following secondary sexual characteristics were selected: black thorns, developed forelimbs, and amplexus reflex. Spermiation was induced in these animals by applying daily 0.4 μg buserelin acetate hormone (GnRHa) for 7 days, being the semen collected 90 min after the application. The volume, color, vigor, motility, sperm concentration, and spermatozoa morphology were subsequently evaluated. Three animals responded to GnRHa induction, enabling... |
