Historical Development of Reproductive Physiology - Figure 1-2: - 384 – 322 BC – Aristotle- Proposed that the fetus originates from menstrual blood.(1884 years later)- 1562 – Fallopius- Discovered and described the oviduct. (11 years later)- 1573 – Colter- Discovered and described the corpus luteum. (99 years later)- 1672 – de Graaf- Discovered and described the antral follicle(5 years later)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- 1677 – van Leeuwenhoek- Discovered and described spermatozoa in semen(103 years later)- 1780 – Spallanzani- Hypothesizes that spermatozoa were the fertilizing agents and successfully artificially inseminated a dog.(45 years later)- 1825 – Dumas- Proved that spermatozoa were the fertilizing agents. (30 years later)- 1855 to present: Beginning of Modern Reproductive Physiology* (Below is in alphabetical order, not chronological order)- Artificial Insemination - Biochemical Pregnancy Detection- Cloning- Embryo Culture/Transfer- Endocrinology- Estrous Synchronization - Frozen Semen- In-Vitro Fertilization- Sex-Selected Semen & Embryos - Ernest and SterlingII. Cornell Reproductive Physiologists - Sydney Arthur Asdell• Diverse areas of reproduction • Book: Patterns of Mammalian Reproduction- William Hansel • Physiology of the corpus luteum and estrous cycle regulation, cancer therapy.• Didn’t retire till his 70s.- Robert H.
