Human spermatozoa can survive for about 3 to 5 days within the female reproductive tract after ejaculation, depending on various factors such as the cervical mucus environment. Outside the body, sperm viability is significantly shorter, typically lasting only a few minutes to a couple of hours. However, in optimal laboratory conditions, such as in a sperm bank, they can be preserved for much longer through cryopreservation.
Human spermatozoa are longer and have a different shape compared to rat spermatozoa. Additionally, human spermatozoa have a higher motility rate and larger head size in comparison to rat spermatozoa. These differences contribute to the variations in reproductive strategies between humans and rats.
Sorry your human species?? What do you mean????
Male gametes or sperms are known as spermatozoa...
Llamas typically live for about 15-25 years, while humans have an average lifespan of around 70-80 years. To calculate how many llama years equal one human year, we can use the ratio of human lifespan to llama lifespan. Assuming a human lifespan of 75 years and a llama lifespan of 20 years, one human year would be equivalent to approximately 3.75 llama years.
Human I believe
store spermatozoa, transport spermatozoa during ejaculation.
Spermatozoa (sperm) are formed in the testes and mature in the epididymis.
The maximum recorded lifespan for humans is around 122 years. While there is ongoing research on extending lifespan through advancements in medicine and technology, 122 years remains the longest confirmed human lifespan to date.

No, blood cells live the same lifespan no matter how old the human is.
70.12 years
The average lifespan is about 82 years.
