Final answer:
The reference material does not specify the most common lower genital tract malformation in FEMALES but highlights infections like trichomoniasis and candidiasis as prevalent conditions in the female genital tract.
Step-by-step explanation:
The most common lower genital tract malformation found in FEMALES is not explicitly mentioned in the reference material provided. However, discussing the related infections and conditions can provide context. The lower genital tract in females includes the vagina and the external genitalia, such as the labium majora. While the term 'malformation' typically refers to congenital anomalies, the provided information emphasizes infections like trichomoniasis and candidiasis, which are common infectious conditions affecting the female genital tract. Trichomoniasis, caused by the protozoan parasite Trichomonas vaginalis, is the most common nonviral sexually transmitted infection (STI). Candidiasis, typically caused by Candida albicans, can lead to fungal vaginitis. Despite these infections being prevalent, they are not malformations but infections that can lead to complications if left untreated.
