在发现人类卵细胞和精子细胞之前，我们不可能完全理解人类的生殖现象。因而，直到19世纪逝去好久了，医学权威们尽管对怀孕和妊娠怀有各种各样的富有幻想的推测，但是对于其最终大白于天下的真相仍然知之甚少。惟有显微镜的发明以及随后接连的该发明技术的改进，才激励科学家们探测生殖的事实真相。光这一探索过程就经历了近150年。
Conception
- Historical Notes
Human reproduction could not be fully understood before the discovery of human egg and sperm cells.
Thus, until well into the 19th century, medical authorities entertained various fanciful theories about conception and pregnancy that had little to do with the truth as it finally emerged. It was only the invention and subsequent continued improvement of the microscope that enabled scientists to ascertain the facts, a process that took nearly 150 years.
