Article Synopsis
- Cryptorchidism can lead to infertility and testicular cancer, with estrogen signaling being essential for testicle descent and hormonal imbalances contributing to the condition.
- The study aimed to examine the association between specific genetic variations (polymorphisms) in the CYP19 and ESR2 genes and the risk of developing cryptorchidism in children.
- Results showed significant differences in the frequency of certain genotypes and alleles between cryptorchid patients and healthy controls, suggesting that specific variations could increase the risk of cryptorchidism while others may provide protection.
Gonadotropin therapy for mini-puberty induction in male infants with hypogonadotropic hypogonadism: a systematic review.

Context: Congenital hypogonadotropic hypogonadism (CHH) is defined as an isolated deficiency of gonadotropin hormones. Mini-puberty, a transient postnatal activation of the hypothalamic-pituitary-gonadal axis in healthy infants, provides a window of opportunity to diagnose and treat CHH. Currently, in male infants with CHH, testosterone is used to increase phallus size.

Department of Urology, Asklepios Klinik Altona, Hamburg, Germany.
Introduction: Bilateral testicular tumours occur in 3-5% of all cases with testicular neoplasms. In the majority of cases, histology of the two new growths is identical. The time interval between the two neoplastic events rarely exceeds 10 years.

Background: Canine cryptorchidism, manifested by an abnormal testicular position, poses significant health risks and reproductive challenges in affected males. Despite a high prevalence, estimated at up to 10% in the canine population, a comprehensive understanding of its pathogenesis remains elusive. Studies in human cryptorchids and knockout mice have identified key factors involved in testicular descent, including INSL3, RXFP2, and AR.
