Effect of unilateral cryptorchidism on mobility and velocity parameters of sperm in (Bos frontalis) semen

Abstract

KEYWORDS Mithun CryptorchidComputer assisted sperm analysis Motility Velocity parameters ABSTRACTThe present study was conducted to assess the motility and velocity parameters of sperm of normal intact and unilateral cryptorchid mithun bull by computer assisted sperm analyzer (CASA). Twenty ejaculates were collected from cryptorchid (n=10) and normal intact (n=10) bull. The different parameters assessed through CASA were static sperms (SM), Total Motility (TM), forward progressive motility (FPM), Average Path velocity (VAP), Average beat/cross frequency (BCF), Straightness (STR), Average straight line velocity (VSL), Average curvilinear velocity (VCL), Average amplitude of lateral head displacement (ALH), Wobble (WOB), Linearity (LIN), Elongation (EL). The result showed that these CASA parameters differed significantly (p<0.05) between the intact and cryptorchid mithun bull and intact mithun bull has significantly (p<0.05) higher value than cryptorchid mithun bulls. It was concluded that most of the CASA parameters were significantly lower in cryptorchid bulls than intact bull and however, due to the genetic hereditary nature of cryptorchid, these bulls should not be used for breeding purposes.

Assisted reproductive technologies (ARTs) in Mithun (Bos frontalis): What progress has been made so far? An overview

“…In Mithun, vaccination against foot and mouth disease significantly affects semen production and its quality profiles; therefore, the semen collection withholding period is standardized as 2.50 months (Perumal, 2018e; Perumal, Khate, & Rajkhowa, 2013). Unilateral cryptorchidism (Perumal, 2013; Perumal, Chang, Sangma, Khate, & Saminathan, 2016) and scrotal insulation (Perumal, 2018f) have a significant adverse effect on scrotal and testicular biometrics, hormones and semen production and its quality profiles in Mithun; therefore, cryptorchid male and semen collection throughout summer season need to be avoided. Vices such as spontaneous erection and masturbation have non‐significant adverse effects on semen production and its quality profiles in Mithun (Perumal, Vupru, Khate, Veeraselvam, et al, 2013).…”

“…Thus, Cryptorchidism has been associated with abnormal testicular structure and functions [9]. Some studies have reported sperm abnormalities in bucks [7] [8] [10] and other male species [11] [12] [13] with unilateral cryptorchidism.…”
