Vulvovaginal candidosis (VVC) is a symptomatic vaginal yeast infection, especially caused by Candida spp. Although VVC is common among reproductive-age women, prevalence studies notice the uprise of vaginal Candida colonization to 30% during pregnancy by culture, especially in the last trimester. Recent studies have considered it a severe problem due to the emerging evidence showing the association of VVC with a higher chance of pregnancy-related complexities (e.g., preterm labor, premature rupture of membranes, congenital cutaneous candidosis, and chorioamnionitis). In this review, we have reassessed and summarized the prevalence rate of VVC in expecting mothers and analyzed the association of several factors to the increased risk of VVC during pregnancy in different regions of the world. Altogether, these data collected from various studies showed the highest prevalence of VVC during pregnancy, mostly in Asian and African countries (90.38%, 62.2%, and 61.5% in Kenya, Nigeria, and Yemen, respectively). The prevalence rate of VVC during pregnancy was also found to differ with age, gestation period, parity, educational status, and socioeconomic level. Some pregnancy-related factors (e.g., weakened immunity; elevated level of sex hormones, glycogen deposition; low vaginal pH; decreased cell-mediated immunity) and several clinical and behavioral factors can be suggested as potential risk factors of candidosis during pregnancy.
