How I overcame problems in < em > in vitro < /em > fertilisation of livestock animals

Reprod Fertil Dev. 2023 Dec;36(2):27-33. doi: 10.1071/RD23162.ABSTRACTIn my research life of 35years, growing with IETS as a researcher of in vitro maturation and fertilisation (IVM/IVF) of porcine and cattle oocytes, I suffered from hard times related to solving problems that prevented the progress of my research and conferment of my degrees. Many researchers may have similar problems. Thus, I would like to address a few examples of how I overcame these problems related to IVF and help young researchers with similar troubles. There were four main problems to be solved in my experiments. Problem 1: Establishment of IVF using only defined medium in pigs. Problem 2: Establishment of successful in vitro culture (IVC) of IVM/IVF bovine oocytes in defined medium. Problem 3: Low rate of male pronucleus formation in IVM porcine oocytes after IVF. Problem 4: Sedimentation of Ca2+ in the sperm capacitation solution for IVF in pigs. Problem 1 was solved by a lucky accident, in which a sperm suspension that would have otherwise been discarded happened to be successfully used for IVF in pigs. Problems 2, 3 and 4 were solved by communication with scientists whose fields were different from mine, where similar problems had been solved already. Young researchers are encouraged to transcend the boundaries of their research fields and solve problems by interacting with researchers in different fields. There are many good connections or answers around us that may be effective in resolving the ...
