男女生殖器官都可以分为两类:一类是性腺,一类是附性器官。男女生殖器官中的性腺都有双重使命,一是产生精子或卵子;二是分泌性激素。性激素有助于附性器官的发育与生长。附性器官的功能是参与完成性行为和完成新生命的形成与孕育。
Male and female reproductive organs can be divided into two categories: one is the gonads, one is an accessory organ. Gonads in male and female reproductive organs have a double mission, one is to produce sperm or egg; the other is secreted hormones. Sex hormones contribute to the development and growth of attached organs. The function of the accessory organ is to participate in the completion of sexual behavior and the completion of the formation and birth of a new life.
