Y chromosomal infertility is a direct cause of male infertility due to its effects on sperm production, occurring in approximately one in 2000 males. [22] Usually, affected men show no symptoms, although they may have smaller testes.
Testis FNA cytology of the testis correlates well with testis biopsy histology in the evaluation of male infertility. Testis FNA cytology is rapid and safe and provides information not only on the presence or absence of sperm but, when applied in multiple areas like a "map", can precisely localize sperm production.
Azoospermia is the medical condition of a man whose semen contains no sperm. [1] It is associated with male infertility, but many forms are amenable to medical treatment.In humans, azoospermia affects about 1% of the male population [2] and may be seen in up to 20% of male infertility situations in Canada.
Also known as cryptorchidism, undescended testicles occur when one or both testicles fail to fully migrate into the scrotum during development. It can lead to low testosterone, male infertility ...

Cryptorchidism, also known as undescended testis, is the failure of one or both testes to descend into the scrotum. The word is from Ancient Greek κρυπτός (kryptos) 'hidden' and ὄρχις (orchis) 'testicle'. It is the most common birth defect of the male genital tract. [1]
Klinefelter syndrome (KS), also known as 47,XXY, is a chromosome anomaly where a male has an extra X chromosome. [10] These complications commonly include infertility and small, poorly functioning testicles (if present).
Infertility is the most prevalent symptom of Sertoli-cell-only syndrome. Semen examination reveals azoospermia, with sperm density frequently falling to fewer than 1 million sperm per mL. When sperm density falls, the testes exhibit SCO syndrome and hypospermatogenesis.
