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.

- 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. Sperm number and motility are typically the first parameters assessed in a semen sample. Vitality is another commonly assessed parameter, particularly when motility is deemed poor since it allows physicians to differentiate between live non-motile sperm and dead sperm cells. The procedure for determining vitality is to place sperm in a hypotonic solution and observe the specimen under the microscope after a 5-minute incubation. This short incubation time allows for observable cellular changes without causing cell death. What type of microscope would you recommend using to observe sperm cells for this laboratory test and why?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.

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.
- Mumps is a viral infection. The primary symptom of mumps is visible swelling of the parotid gland on either side of the face. However, the virus can also infiltrate the male reproductive system, causing the testes to atrophy. Some effects include oligospermia (low sperm count), azoospermia (no sperm in semen), and asthenospermia (reduced sperm movement). Research treatment options for reduced sperm movement. Describe one option that can be used to aid successful fertilization and explain why it helps.In vitro fertilization (IVF) is a common assistive reproductive technology for couples who are struggling to conceive naturally; however, the success rate of IVF is, at best, about 55%. Researchers seeking to improve the success of IVF need to observe the interaction between sperm and eggs in order to better understand the factors that favour fertilization. Obviously, larger sperm and eggs would be easier to observe, even with the aid of microscopy. On this basis, which of the following vertebrate groups might be a good model for studying IVF because they are likely contain species with large sperm and eggs? Group of answer choices a) fish b) amphibians c) reptiles d) birds e) mammalsWHICH OF THE FOLLOWING STATEMENTS IS CONSISTENT WITH THE RESULTS OF THE EXPERIMENT? Normal prostate epithelium and tumor-derived prostate epithelium produce ATP at equal rates. Tumor-derived prostate epithelium produces ATP at a slower rate than normal prostate epithelium. Normal prostate epithelium produces ATP at a faster rate than tumor-derived prostate epithelium. Tumor-derived prostate epithelium produces ATP at a faster rate than normal prostate epithelium.

Piericidin A inhibits ATP production of normal prostate epithelium. Piericidin only inhibits ATP production of normal prostate epithelium. Piericidin A stimulates ATP production of both normal and tumor-derived prostate epithelium. Piericidin A inhibits ATP production of both normal and tumor-derived prostate epithelium.appearance and liquefication - a normal sample has a gray-opalescent appearance, homogenous and liquefies within 60 min. at room temperature under the influence of prostatic enzymes. liquefaction that does not occur within the normal period may suggest functional disturbance of the prostate. Normal semen samples may contain jelly-like grains which do not liquefy. The sample may appear clear if the sperm concentration is too low. It may also appear brown when red blood cells are present in the ejaculate (haematospermia) Liquefaction time Clinical Implication Within 60 minutes Beyond 60 minutes
