Gonadal dysgenesis If a single or combination of these genes are mutated or deleted, downstream signalling is disrupted, leading to malformation of male external genitalia. SRY acts on gene SOX9 which drives Sertoli cell formation and testis differentiation. An absence in SRY causes SOX9 to not be expressed at the appropriate time or concentration, leading to a deficiency in testosterone and Anti-Müllerian hormone production. Inadequate levels of testosterone and Anti-Müllerian hormone disrupts the development of Wolffian ducts and internal genitalia that are key to male reproductive tract development. The lack of the male associated steroid hormones drives Müllerian duct development and perusal
Male accessory gland infection a more complicated form of MAGI, such as involving more than one site, than those with normal levels. Potential complications include: These complications can result in sexual dysfunction and male subfertility. Male accessory gland infection Male Accessory Gland Infection (MAGI), also known as Male Accessory Gland Inflammation, is a condition with signs of inflammation involving one or more sites in the male genital tract. Diagnosis is made according to parameters defined by the World Health Organization, and it is particularly made in relation to infectious or inflammatory causes of male infertility. Although it is usually caused by infection spreading from
