The database of localization and expression of aquaporins (AQPs) in frozen-thawed bull spermatozoa

The data present research results being part of the OPUS-22 project entitled “In search of new markers of male fertility in cattle. Aquaporins expression in the reproductive organs and sperm of the bulls (Bos taurus)” financed by the National Science Center in Poland (grant no. 2021/43/B/NZ9/00204).
The aim of this part of the project was to identify and localize all AQPs present in bovine cryopreserved sperm and to determine their potential role in the effective use of frozen-thawed semen for cattle fertilization. The evaluation of specific AQP expressions was complemented by an analysis of the basic quality parameters of cryopreserved semen. The concentrations of free amino acids (AA) and biogenic amines (BA), as well as the composition of fatty acids (FA), were also determined in thawed seminal plasma and spermatozoa.
