Aim. This study aimed to describe a distinct subpopulation of azoospermic patients with isolated elevation follicle-stimulating hormone (iFSH) and poor outcomes microdissection testicular sperm extraction (microTESE). Materials methods. A retrospective analysis microTESE was conducted among 565 non-obstructive azoospermia (NOA). Testicular pathology assessed by the dominant histological pattern...
BACKGROUND Most patients with testicular cancer are infertile; thus, the preservation of the sperm after surgery is an important factor to consider. We report two cases of bilateral testicular cancer in patients who underwent bilateral higher orchiectomy and simultaneous testicular sperm extraction. CASE PRESENTATION Two Asian-Japanese men were referred to our hospital with bilateral testicul...
Klinefelter syndrome, 47,XXY (KS), is the most frequent sex chromosome aberration in males, affecting 1 in 660 newborn boys. The syndrome is characterized by testicular destruction with extensive fibrosis and hyalinization of the seminiferous tubules resulting in small testes, hypergonadotropic hypogonadism, and azoospermia in the majority of cases. Until recently, infertility was considered an...
Testicular sperm extraction (TESE) associated with intracytoplasmic sperm injection has allowed many men presenting non-obstructive azoospermia to achieve fatherhood. Microdissection TESE (microTESE) was proposed as a method to improve sperm retrieval rates in these patients; however, there have been failures. Little is known about whether microTESE leads to spermatogenic alterations in the con...
BACKGROUND Klinefelter syndrome (KS) is the most common sex chromosomal disorder in males and historically patients have been labeled as sterile. After the introduction of microdissection testicular sperm extraction (micro-TESE), successful sperm retrievals for intracytoplasmic sperm injection (ICSI) have been reported. MATERIALS AND METHODS A retrospective study was undertaken on ten patient...
