noun
spermatocyte
A biological term for a male germ cell in the process of meiosis. Used in medical and scientific contexts.
精母細胞は減数分裂によって精子細胞になる。
Spermatocytes become spermatids through meiosis.
From 精 (sei, 'sperm') + 母 (bo, 'mother') + 細胞 (saibō, 'cell'). The term is a direct calque of the German 'Spermatozyt' or English 'spermatocyte'.
