Program Overview

Within reproductive biology, our research focuses primarily on sheep. Semen can be collected using artificial vagina, by electroejaculation in wild sheep, or from the epididymis. We conduct semen evaluation (motility assessment using a heated stage and phase-contrast microscopy, live/dead and acrosome staining) and cryopreservation. Studies also address reproductive seasonality in rams and ewes.

In collaboration with the University of Veterinary Medicine, we investigated the hormonal background of seasonality and aseasonality in domestic and tropical breeds, as well as its possible modulation. Embryo transfer techniques in sheep are also part of our work. In addition to laparoscopic intrauterine and intratubal insemination, we are developing transcervical insemination methods.

The White Dorper breed was introduced from Canada in the form of cryopreserved embryos and semen. As part of doctoral (PhD) research, a significant domestic population has been established using this genetic material.

Our research topics also include the analysis of external and internal parasites affecting the fertility and performance of small ruminants, as well as the characterization of environmental and health factors influencing their reproductive success. A prospective topic is the embrionic programming.
