Reproduction Among Mammals (1937)

The film “Reproduction Among Mammals” provides a detailed overview of the reproductive processes in mammals, particularly focusing on pigs. It describes the development of sperm in the testes, their journey through the reproductive tract, and the fertilization process involving an egg and sperm. The film illustrates the stages of embryonic development, including the formation of the blastula and gastrula, the development of the nervous and circulatory systems, and the role of embryonic membranes and the placenta. Additionally, it compares the embryonic development of pigs and humans, highlighting similarities and differences, and concludes with the birth process.
