Please Explain! A repeat semen analysis for fertility testing is reported as follows: VOLUME: 3.5 mL SPERM CONCENTRATION: 6 million/mL VISCOSITY: Normal SPERM MOTILITY: 30%—grade 1.0 PH: 7.5 MORPHOLOGY: <30% normal-forms—30 spermatids/100 sperm The results correspond with the first analysis. Which of the test results are abnormal? What is the sperm count on this specimen? What is the spermatid count? Based on the spermatid count, what additional test can be performed?

QUICK HELP I WILL RATE JUST THE ANSWER If the physician of a pregnant woman suspects of chromosomal aberration in the baby at the 23rd week of gestation, which prenatal cyrogenetic test method he/she prefer?

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
select ALL that are TRUE about sperm:☑️Meiosis is suspended twice in sperm development; meiosis of sperm is completed when the sperm penetrates an egg ☑️Both the activity of sperm flagella, and the contraction of uterine muscles, are required to propel sperm to the egg in a timely fashion ☑️Each of the four sperm formed by one meiotic event is genetically unique and haploid ☑️ Sperm secrete testosterone which stimulates sustentacular cells to help their development\

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? Describe what you would expect to observe in the case of a live sperm cell and why? How can you distinguish it from a dead sperm cell in the same sample?
