This work was aimed at determining in vivo levels of oxygen (O2) within the porcine oviduct. 13 gilts (G) and eight sows (S) were used. A left lateral paralumbar laparoendoscopic single-site surgical approach (GelPOINT Advanced, SingleMedical→) was carried out under CO2 pneumoperitoneum. Laparoscopy manoeuvres allowed pulling up the ovary towards the single-site port and upon visual inspection pigs were assorted into preovulatory (PreO) or ...

This work was aimed at localizing and evaluating the expression of endogenous hypoxia markers in the porcine oviduct. Oviduct samples were obtained from reproductive tracts of sows (n=20) in the slaughterhouse. Upon visual inspection of the ovary the samples were allocated into late follicular (LF), early luteal (EL) and late luteal (LL) phases of the estrous cycle. Ampulla and isthmus sections were stained against the following specific primary antibodies: HIF2α, VEGF, F...
