If human sperm are microscopic, then are blue whale sperm larger? If so how large are they?

Gary McLoud, Wiley City, Washington, USA

• "Proportionally the biggest sperm is from a kind of fruit fly and is longer by several times the male fly's own body." So, does he carry it around in a holdall then?

• The Amazonian rangoola dwarf eared mouse has proportionally the largest sperm of any mammal while interestingly enough having the smallest testicles!
