Purpose Allopurinol and FSH injection are applied to reduce ischemia–reperfusion injury and to increase survival rate for ovarian follicles after ovarian heterotopic autotransplantation in mice. Methods Ovarian tissues from 6‐week‐old mice were grafted into back muscle then collected after 3 weeks. A total of five groups were included in this experiment as follows: control group ( n = 5), sham‐operated group ( n = 5), allopurinol treatment group (AP) ( n = 5), follicle stimulating hormone (FSH) treatment group ( n = 5), as well as, allopurinol and FSH treatment group (APF) ( n = 5). We investigated survival, number and development of follicles, vaginal cytology along with plasma malondialdehyde (MDA) concentration in grafted ovary. Results Total follicles count significantly increased in APF group compared with other treatment groups ( p < 0.05). MDA concentration significantly decreased in AP group and APF treatment group compared with sham‐operated group. In AP group, vaginal smears showed presence of cornified epithelial cells three–five day after surgery. Conclusions We demonstrated that allopurinol, as a XO inhibitor, plays an important role in order to decrease ischemia injury and to increase survival rate for follicles. Also, FSH, as a folliculogenesis and angiogenesis factor, increases development of follicles. It seems that allopurinol can cause re‐establishing hypothalamus–pituitary axis and finally can restore estrous cycle earlier than for the sham operated group, so it explains the increasing survival rate for follicles.
