Sperm under a microcsope

A medical student looked at his own sperm under a microscope and filmed the fascinating close-ups on his iPhone. Martin Kristiansen shot the footage of his semen, magnified up to 1, times, to give an insight into the world of reproductive cells. His recording, made in the comfort of his home, shows thousands of the tiny cells darting back and forth full of life. The biomedicine student at Aalborg University in Denmark was shocked to see just how lively his semen was.

The Long, Winding Tale of Sperm Science | Science | Smithsonian Magazine

The presence of sperm-head vacuoles has been suspected to be deleterious to the outcomes of assisted reproductive technology ART. It is difficult to accurately distinguish morphologically abnormal sperm with vacuoles under a light microscope. This study was performed to analyze the result of the observation of sperm-head vacuoles using Papanicolaou staining under a light microscope and whether the male partner's age affects these vacuoles. The criteria for the sperm-head vacuoles were those given in the World Health Organization manual. For the analysis of the age factor, the participants were divided into the following groups: years, years, years, years, and years. The percentage of sperm-head vacuoles increased with normal sperm morphology group A vs. In the case of the age factor, a statistically significant difference was not observed across any of the age groups.

Medical student looks at his own SPERM under a microscope

Plate A is a light photomicrograph of sperm smear and green sperm heads in plate B show damage to sperm DNA under fluoroscent microscopy. Nuclear transfer in Mouse Oocytes: A - lancing of zona pellucida, B and C - removal of germinal vesicle, D - an isolated germinal vesicle. This photo shows a human blastocyst - an embryo days old. This embryo is hatching out of its "shell" to the right.

In his lab, Pitnick engineers the heads of fruit fly sperm to glow a ghostly red and green so that he can observe them moving through dissected female fly reproductive tracts. He hopes his work will help reveal how sperm behave within female bodies, an area of research that's still in its relative infancy. These kinds of innovations could one day explain the great diversity of sperm shape and size across the animal kingdom. These early sperm scientists found themselves tasked with answering the most basic of questions, for instance: Are sperm living animals? Are they parasites?
