Введение. До настоящего времени хромосомная нестабильность у мальчиков с крипторхизмом не изучалась. Тем менее хаотизация генома, проявляющаяся в виде хромосомной нестабильности, рассматривается качестве возможного механизма пороков развития и нарушения функционирования различных систем организма детей. Цель. Анализ нестабильности крипторхизмом. Материалы методы. С помощью цитогенетических молекулярно-цитогенетических (флюоресцентная гибридизация in situ / FISH) методов были исследованы лимфоциты периферической крови 30 врожденными пороками развития, которых наблюдался крипторхизм. Результаты. В ходе цитогенетического анализа 14 (47%) была выявлена численных структурных аномалий, а также особенностей морфологии поведения хромосом. Помимо этого, 1 ребенка обнаружена структурная аномалия (46,ХУ,del(15)(q11.2q13)), 3 (10%) – соматический мозаицизм по численным аномалиям (анеуплоидия аутосом гоносом: 45,Х[3]/46,ХY[37]; 47,XY,+9[9]/46,XY[21]; 45,Х[3]/46,ХУ[27]); 4 (13%) хромосомный гетероморфизм (хромосомные варианты: 46,ХУqh-,15ps+; 46,ХУ,9phqh; 46,ХУ,16qh-; 46,ХУ,1phqh,9phqh). FISH позволил подтвердить наличие уточнить ее уровень (долю аномальных клеток). Среди вышеуказанных форм ведущее место занимало нарушение морфологии, структуры хромосом (преимущественно морфологии/ 7 мальчиков, структурные аномалии 5 анеуплоидия 2 мальчика). Это позволило выдвинуть предположения о том, что может лежать основе возникновения при крипторхизме. Заключение. результате проведенного исследования обнаружено, распространена среди являться одним из ключевых элементов патогенетического каскада, приводящего к этому врожденному пороку. Materials and methods. Using cytogenetic molecular (FISH) techniques, blood samples (lymphocytes) of boys with congenital malformations including cryptorchidism was tested. Results. A analysis revealed chromosomal instability manifested as numerical structural abnormalities well chromosomes morphology behavior features (47%). Additionally, one boy demonstrated a imbalance (46,XU,del(15)(q11. 2q13)); presented somatic mosaicism by anomalies (autosomal gonosomal aneuploidy: 45,X[3]/46,XY[37]; 45,X[3]/46,XY[27]); heteromorphism (chromosomal variants: 46,XUqh-,15ps+; 46,XU,9phqh; 46,XU,16qh-; 46,XU,1phqh,9phqh). allowed confirming the presence instability, specifying its level (abnormal cells proportion). Among above-mentioned forms leading place belonged to morphology, chromosome structure disorders (prevailing morphology/behavior boys, aneuploidy boys). These findings hypothesizing an underlying cause cryptorchidism. Conclusion. This study that is common among may represent key elements pathogenetic cascade this malformation.

Cryptorchidism, or undescended testes, is a common congenital condition that significantly increases the risk of testicular malignancy, particularly germ cell tumors (GCTs), with higher in left testis. Persistent Müllerian Duct Syndrome (PMDS) rare disorder males, where structures such as uterus fallopian tubes are present despite individual having Y chromosome and male external genitalia. The concurrent occurrence cryptorchidism, tumors, PMDS extremely rare, making this case noteworthy. We report 24-year-old history bilateral who presented an abdominal mass intermittent pain. Imaging studies revealed complex suggestive tumor. During surgery, small structure resembling was discovered excised alongside both testes. Histopathological evaluation confirmed mixed GCT consisting yolk sac tumor, seminoma, teratoma arising from Additionally, incidental finding uterine-like consistent PMDS. Postoperatively, patient recovered without complications, tumor markers normalizing within one month. Follow-up imaging physical exams showed no recurrence at six months. This highlights association cryptorchidism emphasizing importance multidisciplinary approach to diagnosis, treatment, genetic counseling, regarding fertility associated conditions.

Exposure to environmental chemicals during fetal development may increase the risk of testicular germ cell cancer (TGCC), but few studies have tested hypothesis. We focused on organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), previously investigated in relation other male reproductive health outcomes. conducted a nested case-control study 332 mother-son pairs, comprising 65 TGCC cases 267 controls, identified from Danish Pregnancy Screening Registry with biobanked serum samples collected pregnant women 1985-1995, when exposure studied was relatively high. quantified seven OCPs 13 PCB congeners maternal by gas chromatography tandem mass spectrometry. diagnoses covariate information were derived nationwide registries. estimated associations between individual their mixture through adapted Cox regression quantile g-computation models. Median age at diagnosis 24.7 years. In main analyses, PCBs showed either slightly higher risks or no association (close Hazard Ratios (HR) 1.00), confidence intervals overlapping unity. simultaneously increasing all chemical concentrations one quartile resulted (HR 1.11, 95 % CI: 0.61; 2.05) after adjusting for confounders. Sensitivity analyses investigating tertiles did not change overall pattern results. Prenatal PCBs, pregnancy serum, associated later TGCC.

Cryptorchidism, which is characterized by the failure of one or both testes to descend into scrotum, presents unique challenges in pediatric and adult populations. It essential provide early diagnosis intervention children, predominantly through orchiopexy, with laparoscopic assistance when required, preserve fertility reduce risks testicular atrophy germ cell cancer. This chapter provides an in-depth classification cryptorchidism, outlining its different types their clinical significance. Cryptorchidism includes congenital forms like true undescended, ectopic, retractile, as well acquired ascending testis. emphasizes contributions genetic, hormonal, environmental factors. Diagnostic techniques, including examination, ultrasound, diagnostic laparoscopy, surgical adjunct hormonal treatments, are discussed. In adults, cryptorchidism frequently goes undetected until complications appear, malignancy, impaired spermatogenesis, atrophy. Management decisions involve weighing benefits orchiopexy against those orchiectomy. The highlights significance detection, personalized treatment strategies, long-term follow-up optimize reproductive, oncologic, psychosocial outcomes throughout lifespan, emphasizing a multidisciplinary approach.

Cryptorchidism, the failure of one or both testes to descend into scrotum, and testicular cancer show a strong correlation in dogs humans. Yet, long-standing medical debates persist about whether location undescended directly causes humans if conditions stem from common origin. Although is prevalent disease dogs, even less known its cause with descent this species. This review investigates relation between these two disorders drawing insights human studies, examines key biomarkers identified thus far. In addition, it explores potential causal links, including impact temperature on maturing cells shared genetic Notably, literature reveals significant differences men reproductive development, histological molecular features tumors, prevalence specific tumor types, such as Sertoli cell tumors cryptorchid germ These disparities caution against using models for research underscore limitations when comparisons The paper concludes by suggesting initiatives enhance our understanding complex interplay cryptorchidism dogs.
