Background: Reports of yeast isolates resistant to traditional antifungal drugs have become common. Similarly, refractory clinical cases treated with these traditional antifungal drugs have also been reported. These cases may or may not be related to pregnancy. Newly developed therapeutic approaches, such as the immunostimulant β-glucan combined with the traditional antifungal agents show promising results. Therefore, knowledge of the effects of these new associations is essential. The aims of this study were to evaluate the effects of the combination of itraconazole and β (1-3) glucan on fertility in female rats and its interference in the development of their offspring, including teratogenic potential.Materials, Methods & Results: A total of 180 female Wistar rats (90 days old) separated into six groups were used (n = 30 per group): Negative Control - treated daily with the volume corresponding to 10 mL.kg-1 of sterile distilled water orally, and 0.25 mL of sterile 0.9% NaCl solution subcutaneously weekly; IT - treated daily with itraconazole at a dose of 10 mg.kg-1 orally, and 0.25 ml of sterile 0.9% NaCl solution subcutaneously weekly; Beta - treated daily with the volume corresponding to 10 mL.kg-1 of sterile distilled water orally, and 0.5 mg of β (1-3) glucan subcutaneously weekly; DT - treated daily with itraconazole at a dose of 10 mg.kg-1 orally, and 0.5 mg of β (1-3) glucan subcutaneously weekly; DT5x - treated daily with itraconazole at a dose of 50 mg.kg-1 orally, and 0.5 mg of β (1-3) glucan subcutaneously weekly; DT10x - treated daily with itraconazole at a dose of 100 mg.kg-1 orally, and 0.5 mg of β (1-3) glucan subcutaneously weekly. The rats were treated before (14 days) and during the mating period (up to 21 days), pregnancy (21 days) and lactation (21 days).[...](AU)
