Semen Analysis. The Microscopic evaluation.

Part 2. Semen Analysis. The MICROSCOPIC evaluation. Have you ever read a Semen analysis report and seen the words: OLIGOZOOSPERMIA, ASTHENOZOOSPERMIA, TERATOZOOSPERMIA… I swear this are not made-up words. But do you know what do they mean? Before we start the Semen Assessment, we must mix well the sample for it to be representative. And then we place a drop of the sample on the counting chamber were will perform the Sperm Concentration and Motility. 1. Sperm Concentration. The Sperm Concentration is a measurement that indicates how many millions of sperm cells are present per millilitre of semen. And we use the term OLIGOZOOSPERMIA when there´s less than 15 million sperm cells per millilitre of semen. 2. Sperm Motility. There are three types of Sperm Motility: Progressive, Non-progressive and Immotile. - Progressive motility refers to sperm that are swimming in straight lines or in very large circles. There are also two types of Progressive Motility: Rapidly progressive and Slow progressive. - Non-progressive refers to sperm that move but don't progress (they look like maracas), and the others just swim in tinny little circles. - Immotile refers to sperm that do not move at all. We use the term ASTHENOZOOSPERMIA when there is less than 32% of Progressive sperm cells. 3. Sperm Morphology. A normal sperm cell consists of an oval head shape, a slender midpiece that is aligned with the sperm head, and a tail with a uniform calibre along its length and thinner than the midpiece. So, when we assess the sperm morphology, we are looking at this three parts of the sperm cells, to see if there´s any defects. - Which are the HEAD defects? Some of the head defects are different head shapes (Tapered, pyriform ‘’pear shaped´´ and amorphous). And also an Acrosome that is less than 40% or larger than 70% of a normal head area. And did you know that sperm cells can also have two heads? - Which midpiece defects can we find? We can find a bent neck, an asymmetrical insertion to the head, a thick insertion or a thin insertion. - Which tail defects can we find? We can find short, bent or coiled tails. An did you know that sperm cells can also have two tails? And we use the term TERATOZOOSPERMIA when there is less than 4% of Normal forms. #semenanalysis #sperm #spermatozoa #oligozoospermia #spermcount #asthenozoospermia #spermmotility #teratozoospermia #spermmorphology #andrologist #embryologist #ivf #ivfjourney #fertility #infertility #fertilityjourney #infertility #fertilityclinic #embryologist #laboratory #andrology #maleanatomy #male #foryou
