A motile sperm organelle morphology examination (MSOME) is a particular morphologic investigation wherein an inverted light microscope equipped with high-power optics and enhanced by digital imaging is used to achieve a magnification above x6000, which is much higher than the magnification used habitually by embryologists in spermatozoa ...
The slide is placed under a compound light microscope for sperm observation. If sperm are present, the heads will stain red and the mid-piece and tail stain green. [8] However, not all males release sperm in their semen. If a male is aspermic or oligospermic, they either have no sperm or a low sperm count. [10]

In mammals, the sex of the offspring is determined by the sperm cell: a spermatozoon bearing an X chromosome will lead to a female (XX) offspring, while one bearing a Y chromosome will lead to a male (XY) offspring. Sperm cells were first observed in Antonie van Leeuwenhoek's laboratory in 1677. [2] Human sperm under microscope
The presence of abnormally-shaped sperm can negatively affect fertility by preventing transport through the cervix and/or preventing sperm from adhering to the ovum. Achieving a pregnancy may be difficult. [3] In testing for teratozoospermia, sperm are collected, stained and analyzed under a microscope to detect abnormalities.
Sperm cells with artificially induced acrosome reactions may serve as positive controls. For fluorescence microscopy, a smear of washed sperm cells is made, air-dried, permeabilized, and then stained. Such a slide is then viewed under the light of a wavelength that will cause the probe to fluoresce if it is bound to the acrosomal region.
Positive fern test with amniotic fluid as seen under the microscope. The fern test is a medical laboratory test used in obstetrics and gynecology.The name refers to the detection of a characteristic "fern like" pattern of vaginal secretions when a specimen is allowed to dry on a glass slide and is viewed under a low-power microscope.
