Answer :
Final answer:
Mice have been used as the pioneering species for the study of fertilization, barrier contraception methods, and artificial insemination. They were chosen due to their short lifespan and fast reproductive cycle.
Explanation:
The statement is true. Mice have indeed been used in all the mentioned components of fertility and contraception research. Fertilization, a process that requires both eggs and sperm, has been extensively studied in mice due to their short lifespan and fast reproductive cycle. Mice were also the first animals to have barrier contraception methods tested on them. Moreover, the technique known as artificial insemination, where sperm is physically placed into the female reproductive tract, has been initially demonstrated in mice.
