Klinefelter syndrome is not an inherited condition. The extra X chromosome comes from the mother in approximately 50% of the cases. Maternal age is the only known risk factor. Women at 40 years have a four-times-higher risk of a child with Klinefelter syndrome than women aged 24 years. [15] [35] [36]
A closeup of an erect micropenis with a tape measure displaying length. Of the abnormal conditions associated with micropenis, most are conditions of reduced prenatal androgen production or effect, such as abnormal testicular development (testicular dysgenesis), Klinefelter syndrome, Leydig cell hypoplasia, specific defects of testosterone or dihydrotestosterone synthesis (17,20-lyase ...
It can be considered a form or variant of Klinefelter syndrome (47,XXY). [11] Individuals with this syndrome are typically mosaic, being 49,XXXXY/48, XXXX. [4] It is genetic but not hereditary, meaning that while the genes of the parents cause the syndrome, there is a small chance of more than one child having the syndrome.
Other malformations of the brain and skeleton may also occur. The syndrome includes intellectual disability that is usually severe or moderate. So far, the syndrome has only been diagnosed in girls and in boys with two X chromosomes (Klinefelter syndrome). [3] Those with Aicardi syndrome are in need of various specialist and habilitation instances.
These men have low testosterone levels due to specific medical conditions, such as genetic disorders like Klinefelter syndrome or tumors that have damaged the pituitary gland. [22] The FDA granted the approval of Jatenzo to Clarus Therapeutics. [22] [51] In March 2022, testosterone undecanoate (Tlando) was approved for medical use in the United ...
Turner syndrome results from a single X chromosome (45,X or 45,X0). Klinefelter syndrome, the most common male chromosomal disease, otherwise known as 47,XXY, is caused by an extra X chromosome. Edwards syndrome is caused by trisomy (three copies) of chromosome 18. Down syndrome, a common chromosomal disease, is caused by trisomy of chromosome 21.

Sertoli cell-only syndrome (SCOS), also known as germ cell aplasia, is defined by azoospermia where the testicular seminiferous tubules are lined solely with sertoli cells. [2] Sertoli cells contribute to the formation of the blood-testis barrier and aid in sperm generation.
