the mares and stallions involved and on the quality of breeding management. Of course, …

The role of cultural heritage conservation has proven beneficial for the development of cities
and communities. However, a lack of systematic assessment methodologies for adequate …

During sexual reproduction, the sperm and oocyte must fuse before the production of a
diploid zygote can proceed. In mammals such as equids, fusion depends critically on complex …

The main goal of this study was to investigate whether and at what level damage of paternal
DNA influences fertilization of oocytes and early embryonic development. We hypothesized …

In this study attempts were made to improve the survival rates of bull spermatozoa after
freezing/thawing and to clarify the importance of certain agents to the cryopreservation of …

The primary aim of this study was to establish a flow cytometric technique for determining
the capacitation status of stallion spermatozoa. To this end, a flow cytometric technique that …

The aim of this study was to develop a method for spermatogonial stem cell transplantation
into the bovine testis. Five-month-old Holstein–Friesian calves were used and half of the …

Mammalian sperm cells are activated prior to fertilization by high bicarbonate levels, which
facilitate lipoprotein-mediated cholesterol efflux. The role of bicarbonate and cholesterol …

The effect of low temperatures on the ultrastructure of the plasma membrane of bull and boar
spermatozoa was investigated. Cold-induced changes in the organization of sperm plasma …

The occurrence of pregnancies and births after embryo transfer (ET) of in vivo produced
embryos is generally more successful compared to that of embryos produced in vitro. This …
