sperm morphology
Head
Midpiece
Principle piece
Fertilization
Sperm production
endocrine regulation of the testicle
mitotic divisions of spermatognia
meiotic division resulting in haploid spermatid
morphologic transformation of spermatids into spermatozoa
Testicular function
Pulsatile GnRH secretion
high conc. of T in seminiferous tubules
Low concentration of T in systemic blood
Adequate LH receptors in Leydig cells
Measuring SC
wide variation in breeds
High heritability 0.42-0.88
responds rapidly to selection pressure
male offspring mature sooner
