Ribosomes are like small factories whose task is to make proteins in cells. Though it was believed that, throughout the different kingdoms, ribosomes were all alike, it turns out that some differ slightly in their makeup and are found only in certain kinds of cell - presumably because they synthesize proteins particular to these cells. One such ribosome has been discovered in sperm cells, along with a protein known as large ribosomal subunit protein eL39-like*, or RPL39L.
