Clinical aspects of 49 infertile males with 45,X/46,XY mosaicism karyotype: A case series
Abstract
Disorders of sex development (DSD) are congenital abnormalities as an atypical development process in either gonadal or chromosomal structure. It is the cause of the abnormality in phenotype and characteristics. Chromosomal analysis plays an important role in the DSD determination. 45,X/46,XY mosaicism is a rare karyotype, and its prevalence is about 1.5 in 10,000 newborns. It affects the growth, hormonal balance, gonad development and histology. All data such as height, male general appearance, testis size and volume, external genitalia, spermogram and hormonal levels, testis pathology, Y chromosome microdeletion and karyotype, and assisted reproductive technology (ART) outcome were recorded based on patients profile and history. We investigated 64 infertile males with 45,X/46,XY mosaicism. Fifteen cases who had structural abnormalities in Y chromosome were excluded. From 49 available spermogram, 21 cases reported as azoospermic men, while 28 of them classified as nonazoospermic patients in which four of them displayed normal spermogram. According to hormonal evaluation, there were no significant differences between azoospermic and nonazoospermic groups. In azoospermia, only three couples underwent an ART cycle in which all of them failed. From 14 nonazoospermic cases who entered into the ART cycle, three cases experienced a successful pregnancy that one of the prosperous outcomes was twins. In 45,X/46,XY cases, both 45,X and 46,XY cell lines are seen. Various distributions…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
