Healthy sperm: Improving your fertility - Mayo Clinic

Lumpy, "gelatinous", "clotted", or globulous semen may be quite frightening or worrying to men who experience it, particularly if their semen's appearance has recently changed. What are the possible causes of lumpy semen, and do you need to see a doctor? Healthy, normal semen comes in a rather wide variety of colors, textures, and scents. Hence, a sudden change in the appearance of one's semen does not automatically signify a medical condition. Semen is composed of a large variety of different substances, of which only a small percentage is sperm. One of these substances is protein, which assists with the process of the semen's coagulation thickening and liquefaction. If your semen suddenly has a lumpy appearance after you have not ejaculated for a longer period of time weeks or months , this is your most likely culprit, something that will be confirmed if engaging in more regular sexual intercourse or masturbation solves the problem.

Purpose of review: The classification of morphologically normal sperm has been progressively redefined. Concurrently, our understanding of the significance of sperm morphology in relation to male factor infertility has evolved. In this review, we will discuss the evolution of sperm morphology assessment and factors that contribute to its measurement variability. Recent findings: There is a lack of consensus on sperm morphology classification, technique, and inter-observer grading variability.
