Sperm Maturation and Transport through the Excurrent Ducts Sperm transit time Upon release from the testis, sperm undergo transit through the efferent ducts and the epididymis. 7 for several of the economically important species. g. daily; Amann, 1981). Maturational changes and the acquisition of fertility Spermatozoa are not fertile upon release from the testis, but undergo maturation within the epididymis. Epididymal secretions appear to play a critical role in the maturation process, which includes the acquisition of motility, changes in sperm membranes that permit binding to the zona pellucida of the oocyte, Sperm Production and its Harvest nuclear decondensation and other changes (Cooper, 1995).
Thus, sperm output that is frequently collected from a male provides an excellent method for estimating DSP. It offers the advantage of not requiring the removal of testicular tissue. g. assessment of seminal quality after a single dosage with an anthelmintic). Typical sperm output of economically important species Sperm production varies greatly among individuals both within and among species. Several factors contributing to such variability within species have already been described, including inherent differences in testis size and the influences of variables such as age, season (in some species), environmental factors, drugs, etc.
Similarly, if a male continues to ejaculate at a high frequency, the EGR will ultimately be depleted. At that point, DSO will be limited by and equal to DSP. These concepts have important implications relative to conventional breeding soundness examinations, and for the management of males to maximize the sperm harvest, which are discussed below. Sperm Harvest – Maximising DSO and Seminal Quality Seminal quality and sperm number in ejaculates taken after sexual rest The first ejaculate(s) taken after sexual rest usually contains very large numbers of sperm.
