In recent years, Ukraine has seen a significant deterioration in the reproductive health of women in the face of declining birth rates. One of the main causes of comorbidity of infertility and background pathologies is the insufficient supply of a woman's body in the pre-pregnancy period with micronutrients – folate, vitamins, myo-inositol and others. This increases the risk of complications during pregnancy and childbirth and congenital malformations.Literature analysis showed that myo-inositol in combination with folate are an extremely important way to prevent fertility disorders, complications of pregnancy and childbirth, congenital malformations and support the reproductive health of the next generation. Myo-inositol in combination with folic acid promotes the effects of luteinizing and follicle-stimulating hormones, normalization of ovarian function, oocyte quality, trophoblast invasion during blastocyst attachment, prevention of congenital malformations by neutralizing the action of homocysteine with metafolin in the pregravid period and during pregnancy and assisted reproductive technologies, reducing the incidence of miscarriage, preeclampsia and other complications. The neuroprotective effect of myo-inositol indicates the importance of its use for fetal neuroprotection in late gestation, especially in hypoxia.Fertifolin, which contains an improved combination of natural nutrients as myo-inositol 1000 mg and folic acid 100 µg in the form of metafolin (calcium L-methylfolate), successfully copes with this goal. Metafolin has greater bioavailability and more actively helps to increase the level of folate in blood plasma, in contrast to folic acid. Metafolin is characterized by fewer drug interactions and less often masks the symptoms of B12-deficient anemia, reduces the risk of anemia, placental dysfunction, malformations of the neural tube. Fertifolin is also effectively used as an adjunct in polycystic ovary syndrome and in assisted reproductive technology protocols.
