What protein or chemical in sperm or seminal fluid causes it to naturally fluoresce under UV light?

The fluorescence of sperm and seminal fluid under UV light is primarily due to the presence of the enzyme flavin adenine dinucleotide (FAD) and other fluorescent proteins such as protamines and lipofuscin. These molecules have natural fluorescence properties that allow them to emit light when exposed to ultraviolet light.

What is the mucsular dystrophy?

Macular Dystrophy or vitelliform dystrophy is a genetic eye disorder that can cause progressive vision loss. This disorder affects the retina, specifically cells in a small area near the center of the retina called the macula. The macula is responsible for sharp central vision, which is needed for detailed tasks such as reading, driving, and recognizing faces.DiagnosisVitelliform macular dystrophy causes a fatty yellow pigment (lipofuscin) to build up in cells underlying the macula. Over time, the abnormal accumulation of this substance can damage cells that are critical for clear central vision. As a result, people with this disorder often lose their central vision and may experience blurry or distorted vision. Vitelliform macular dystrophy does not affect side (peripheral) vision or the ability to see at night.

Also, hazel eyes may appear to shift in color and consist of flecks and ripples; while amber eyes are of a solid gold hue.The eyes of some pigeons contain yellow fluorescing pigments known as pteridines. The bright yellow eyes of the Great Horned Owl are thought to be due to the presence of the pteridine pigment xanthopterin within certain chromatophores (called xanthophores) located in the iris stroma.In humans, yellowish specks or patches are thought to be due to the pigment lipofuscin, also known as lipochrome.Her eyes are not hazel there amber colored
