Is addition or removal of seminal plasma able to compensate for the dilution effect of buffalo semen? Andrologia 2021; 53:e14123.

Abstract
The present study aimed to compensate dilution effect using additional seminal plasma (SP) in conventional (80 million (M) spermatozoa/ml) dose and low spermatozoa/dose (8M spermatozoa/ml). We also attempted to confirm whether removal of SP before the extension of ejaculates affects post-thaw sperm quality of buffalo semen. For this, semen ejaculates (N = 15) were divided into four groups: control (CON), removal of SP by centrifugation (NSP), resuspension of the centrifuged semen pellet into SP (CEN) and extra supplementation of SP (ESP). All groups were diluted into two different semen doses to 20 and 2M spermatozoa/0.25 ml using tris egg yolk extender and subsequently cryopreserved. We found that neither addition nor removal of SP affected sperm motility, kinematics, longevity, mitochondrial superoxide production and high mitochondrial membrane potential (MMP). Further, the addition or removal of SP was not able to compensate dilution effect in 2M groups resulting in a significantly (p < .05) reduction in sperm motility, kinematics, sperm longevity, membrane integrity, MMP, and an increase production of mitochondrial superoxide. In conclusion, it appears that role of SP in the sperm cryopreservation process is insignificant.

Abstract
Little is known of the different freezing and thawing techniques for post-thaw survival of spermatozoa in Sambar deer. So, this study determined the effect of seminal plasma, egg yolk and glycerol extenders and their concentrations, plus cooling, freezing, and thawing protocols on the post-thaw quality of their semen. Semen samples were collected by electro-ejaculation from four Thai Sambar deer stags (Cervus unicolor equinus). As evaluated by post-thaw progressive motility and acrosome integrity removal of seminal plasma was beneficial; Tris-egg yolk was the most efficient extender; a 20% egg yolk concentration was better than the 0%, 10%, or 30%; and a 3% glycerol concentration was better than 5%, 7%, or 9%. Using the optimum dilution techniques, semen was loaded in 0.5 ml plastic straws. Cooling times from ambient temperature to 5°C in 3 hr resulted in higher post-thaw progressive motility and acrosome integrity than 1, 2, or 4 hr. Suspending the straws 4 cm above the surface for 15 min before plunging into liquid nitrogen was better than suspending at 2 or 6 cm. For thawing frozen semen, an intermediate thawing (50°C, 8 sec) protocol was more effective than the slower (37°C, 10 sec) or faster (70°C, 5 sec) thawing rates. Timed insemination following estrus synchronization of 10 hinds resulted in six confirmed pregnancies at 60 days. Five hinds delivered live fawns. This study provides an effective approach for semen cryopreservation and artificial insemination (AI), which should be valuable to scientists for genetics and reproductive management of Sambar deer in developing countries.
