According to a 2013 review cited by Healthline, semen contains various nutrients, including zinc, fructose, and traces of Vitamin B-12. However, the question of whether sperm contains vitamin A is more nuanced, as this essential nutrient plays a far more significant role in the production of sperm rather than its final composition.

According to scientific studies, the endogenous vitamin B12 content in human seminal plasma is remarkably low, typically ranging from 88 to 699 pg/mL. While this amount is a miniscule fraction of the body's total vitamin B12, its role in reproductive health is a frequent area of research, with correlations noted between systemic B12 levels and male fertility.

Approximately 80% of the 20,000 protein-coding genes in the human genome are expressed in adult testes, highlighting the organ's intense protein synthesis activity. This biological fact prompts the question: how much protein do human testes and the associated reproductive fluids actually contain?

According to the Mayo Clinic, fructose is produced by the seminal vesicles and is a crucial energy source for sperm motility. The question, 'Is fructose found in human sperm?', is often asked due to confusion about which component of semen contains the sugar. This article clarifies its role and significance in male reproductive health.

No, bone marrow does not contain sperm; sperm production, known as spermatogenesis, occurs exclusively in the testes, a key part of the male reproductive system. This common misconception can be cleared up by understanding the distinct roles of the skeletal system's bone marrow and the male reproductive organs.

According to scientific analysis, an average human ejaculate contains a surprisingly small amount of protein, typically less than a quarter of a gram. This minuscule figure provides context for the question of how much protein does one shot of sperm have, as the total nutritional contribution is negligible.
