EVALUATION OF THE EFFECT OF HYPOTAURINE ON IN VITRO FERTILIZATION IN THE OOCYTES OBTAINED OF THE EXPERIMENTAL POLYCYSTIC OVARY SYNDROME IN MICE: AN EXPERIMENTAL STUDY

In this experimental study, the effect of hypotaurine on in vitro fertilization and fertility of oocytes from mice with experimental polycystic ovary syndrome was designed and performed.

In this experimental study, NMRI mice aged 6 to 8 weeks were used. The mice were divided into two groups, control and experimental PCOS. For induction of experimental PCOS, Estradiol Valerate (100 mg/kg, IP) was injected. Then, for ovulation, the injection was performed first with 7.5 IU PMSG in the volume of 0.1 ml and 46-48 hours later with 7.5 IU hCG in the volume of 0.1 ml. Finally, 0/1, 1 and 10 μM curcumin were added to the culture medium of oocytes of PCOS group and development in different groups were evaluated (P <0.05).

Most of the arrested embryos had a high percentage of lysis and fragmentation and the arrested embryos were type I and II. The addition of hypotaurin reduced the rate of lysis and fragmentation and decreased the percentage of arrested embryos. Lesser arrested embryos were type III (P <0.05). This study showed that 1 μM hypotaurin increased fertilization percentage and 10 μM hypotaurin increased the percentage of two-cell embryos and also increased the percentage of blastocytes (P <0.05).

The results showed that addition of certain concentrations of hypotaurin as an antioxidant, improved and increased the fertilization rate and the percentage of two-cell embryos. It can also be helpful in increasing the percentage of blastocysts.
