Hypogonadism and Cryptorchidism

Frontiers in Endocrinology, 2020
Congenital cryptorchidism (undescended testis) is one of the most common congenital urogenital malformations in boys. Prevalence of cryptorchidism at birth among boys born with normal birth weight ranges from 1.8 to 8.4%.

Predictive factors for successful sperm retrieval by microdissection testicular sperm extraction in men with nonobstructive azoospermia and a history of cryptorchidism

Asian Journal of Andrology, 2022
This study aims to explore the factors influencing the success rate of the microdissection testicular sperm extraction (Micro-TESE) in patients with nonobstructive azoospermia (NOA) and cryptorchidism.

A case-cohort study of perinatal exposure to potential endocrine disrupters and the risk of cryptorchidism in the Norwegian HUMIS study

Environment International, 2021
Background: Exposure to endocrine-disrupting chemicals (EDCs) during the critical period of testicular descent may increase the risk of cryptorchidism and male fertility.

Cryptorchidism and puberty

Frontiers in Endocrinology
Cryptorchidism is the condition in which one or both testes have not descended adequately into the scrotum. The congenital form of cryptorchidism is one of the most prevalent urogenital anomalies in male newborns.

Decoding the pathogenesis of spermatogenic failure in cryptorchidism through single-cell transcriptomic profiling

Cell Reports Medicine
Summary: Cryptorchidism, commonly known as undescended testis, affects 1%–9% of male newborns, posing infertility and testis tumor risks. Despite its prevalence, the detailed pathophysiology underlying male infertility within cryptorchidism remains ...

Genetics of cryptorchidism and testicular regression.

Best practice & research. Clinical endocrinology & metabolism, 2022
Cryptorchidism, i.e., undescended testis, is one of the most common genital malformations in newborn male babies. The birth rate of cryptorchidism varies from 1.6 to 9.0 %.

Transcriptomic Analysis of Testicular Gene Expression in a Dog Model of Experimentally Induced Cryptorchidism

Cells, 2022
Cryptorchidism, a condition in which testes fail to descend from the abdomen into the scrotum, is a risk factor for infertility and germ cell cancer. Normally, tight junctions between adjacent Sertoli cells in the testes form a blood–testes barrier that ...

Viral infections that alter estrogen levels during pregnancy may contribute to the etiology of cryptorchidism

Basic and Clinical Andrology, 2021
Résumé La cryptorchidie est. aussi fréquente que le diabète de type 2 ou la maladie cœliaque. Les garçons atteints de cryptorchidie congénitale ont un risque élevé d’infertilité et de cancer des testicules.
