A couple both in their late thirties are undergoing evaluation of infertility. A semen specimen was collected at home and brought to the lab for routine testing. The following are the Semen analysis results: Physical exam: Color-gray ; volume 4.5ml; liquefaction-50mins; viscousity- 0 Microscopic exam: motility-70%, concentration: 15M sperm/ml; morphology 70% normal; vitality-60%; leukocytes- 0.8 x (10 to the 6th) cell/ml 1. What are the abnormal results? 2. Do any of the results obtained suggest improper collection or lab error? 3. which of the following results suggest male infertility? Suggest chemical test, based on the given results, that can be used to evaluate functional integrity of the male reproductive system.

When investigating fertility concerns, a common course of action is to rule out sperm cell-related causes of infertility first since obtaining the relevant specimens is generally less invasive. Vitality is another commonly assessed parameter, particularly when motility is deemed poor since it allows physicians to differentiate between live and dead sperm cells. Describe what you would expect to observe (after using the microscope) in the case of a live sperm cell and why? How can you distinguish it from a dead sperm cell in the same sample?
