The aim of this article was to determine the impact of oxygen concentration during in vitro culture of human oocytes and embryo on fertilisation, implantation, pregnancy, gestation and abortion rates. Women between 20-48 years old who are seeking for infertility treatments and intracytoplasmic sperm injection participated in this experiment. Embryos were randomly allocated for incubation under three different oxygen conditions, the first group was subjected to 20% Oxygen in air. The second group was initially subjected to 20% Oxygen in air, then on the following day (day 2) 5% Carbon Dioxide and 90% Nitrogen gas was introduced into the system while Oxygen was decreased to 5%. Finally, the third group was subjected to 5% Carbon Dioxide gas and 90% Nitrogen gas throughout the experiment. | The aim of this article was to determine the impact of oxygen concentration during in vitro culture of human oocytes and embryo on fertilisation, implantation, pregnancy, gestation and abortion rates.

Article 1 PMID 26131222 The aim of this article was to determine the impact of oxygen concentration during in vitro culture of human oocytes and embryo on fertilisation, implantation, pregnancy, gestation and abortion rates. Women between 20-48 years old who are seeking for infertility treatments and intracytoplasmic sperm injection participated in this experiment. Embryos were randomly allocated for incubation under three different oxygen conditions, the first group was subjected to 20% Oxygen in air. The second group was initially subjected to 20% Oxygen in air, then on the following day (day 2) 5% Carbon Dioxide and 90% Nitrogen gas was introduced into the system while Oxygen was decreased to 5%. Finally, the third group was subjected to 5% Carbon Dioxide gas and 90% Nitrogen gas throughout the experiment. To determine its ability to yield a successful pregnancy, the embryo must be cultured and incubated for 2-6 days in a defined medium. Embryos cultured in 5% Oxygen in air presented highest rates of fertilization and implantation compared to those incubated in 20% Oxygen in air. Meanwhile, embryos cultured in 20% Oxygen in air also presented high rates of fertilisation, high quality embryo and implantation. Intracytoplasmic sperm injection derived embryos cultured in 20% Oxygen in air resulted in lower rates of cleavage compared to those of from the second group, from 20% - 5% Oxygen in air. These results were consistent with the data previously published.
