OBJECTIVE: To evaluate the efficacy of a treatment with Myo-inositol (MI) plus melatonin and vitamin D3 in women underwent intra cytoplasmatic sperm injection (ICSI).
PATIENTS AND METHODS: 100 women undergoing ICSI procedure were enrolled and randomly divided 1:1 in two groups. The study group was treated with 2 g MI, 50 mg Alpha-Lactalbumin (alpha-LA) and 200 µg folic acid in powder every morning for 6 months (3 months before oocyte pick up and 3 months after ICSI); the same patients underwent treatment with 600 mg MI, 1 mg melatonin plus 200 µg folic acid during the evening for 3 months before oocyte pick up; subsequently the pick up these patients were treated with 600 mg MI, 200 µg folic acid, 1 mg melatonin, 50 µg vitamin D3 as cholecalciferol until the 12th week of gestation. The control group was treated with 200 µg folic acid twice a day.
Clinical pregnancy rate was evaluated as primary outcome, followed by blastocyst and oocyte quality, as well as gestational period as secondary outcomes.
RESULTS: Treatment significantly improved blastocyst and oocyte quality in the study group, achieving the 42% of clinical pregnancies vs. 24% in the control group, even though the course of pregnancy did not significantly differ between the groups. However, the mean gestational period was shorter in the control group.
CONCLUSIONS: The supplementation of MI in combination with melatonin in the first 3 months before oocyte pick up and with vitamin D3 in the further 3 months could represent an innovative support for all those women undergoing ICSI.
