(b) 60 per cent sperm must have normal shape and 40 per cent must have acrosome. (c) 60 per cent sperm must have normal shape and 40 per cent must have vigorous motility. (d) None of these
What are the two major changes to sperm after they pass through the epididymis? Describe the two mechanisms for sperm movement through the cervix. Describe either one of the two factors involved in sperm selection at the uterotubal junction that enables sperm to enter the oviduct.

Text: Using a 1:10 dilution of a specimen with a volume of 2 mL, 400 sperm are counted in four large squares (WBC squares) of the Neubauer hemocytometer. Calculate the sperm concentration and the sperm count. Using the following information, answer the next 3 questions: Volume: 2.5 mL Viscosity: 4 pH: 9.0 Sperm concentration: 40 million/mL Sperm motility: 20% - Grade 1.0 Sperm morphology: <30% abnormal 23. Which parameters are abnormal? 24. Which abnormal parameters are affecting the motility? 25. Which abnormal parameter is affecting the viscosity?
