Kinematic changes during the cryopreservation of boar spermatozoa.
The present study evaluates the effect that various steps of a conventional cycle of cryopreservation have on the patterns of movement exhibited by boar spermatozoa. Sperm-rich ejaculate fractions collected from 24 mature fertile boars (1 ejaculate per boar) were cryopreserved following a standard freeze-thaw procedure with 0.5-mL plastic straws. Overall sperm motility and the individual kinema...
متن کاملCryopreservation Effect on Expression of Sex Steroid Receptors of Boar Spermatozoa
This study aimed to investigate the expressions of estrogen receptor (ER) alpha, ER beta, and progesterone receptor (PR) during semen cryopreservation, to evaluate the correlation among ER, ERβ, PR, capacitation, acrosome reaction, and semen quality parameters, and to investigate the effect of different concentrations of L-cysteine on the expressions of ER, ERβ, and PR. Semen samples were col...
متن کاملCryopreservation of Boar Spermatozoa: An Important Role of Antioxidants
Artificial insemination (AI) is one of the first reproductive biotechnologies has been established and developed in the pig production system. In most case, liquid stored semen or fresh semen is used for AI in commercial swine herds (Wagner and Thibier, 2000). The use of FT boar semen for AI is limited due to the low fertility outcomes compared to extended fresh semen (Johnson et al., 2000; Wag...
متن کاملEvaluation of l-glutamine for cryopreservation of boar spermatozoa.
The aim of the present study was to evaluate the protective effect of L-glutamine (L-Gln) against cryopreservation injuries on boar sperm. In Experiment 1, L-Gln from 20 to 80 mM was evaluated as a supplement for a standard freezing extender (egg yolk - EY - 20%, and glycerol 3%). No significant improvement (P>0.05) was obtained for any post-thaw sperm parameter assessed (objective sperm motili...
متن کاملCryopreservation of Boar Spermatozoa: the Curious Functions of Seminalplasma during Freezing or Thawing
There are various advantages, such as the preservation of genetic resources, an improvement of the reproduction performance in summer, long-distance transportation of semen and the possibility of progeny test, in the cryopreservation technique of boar semen. However, cryopreserved boar spermatozoa have not been routinely available to swine artificial insemination (AI) due to the lower conceptio...
