OBJECTIVES To assess if there is an age group where the occurrence of persistent processus vaginalis is more frequent in patients with cryptorchidism. MATERIALS AND METHODS We studied 24 fetuses with gestational age between 23 and 35 weeks postconception (control group) and 102 patients (137 testes) with cryptorchidism aged between 1 and 33 years (mean 10.3 years). We considered 2 situations ...

BACKGROUND Prenatal exposure to alcohol can adversely affect the fetus. We investigated the association between maternal alcohol consumption during pregnancy and cryptorchidism (undescended testis) among newborn boys. METHODS We examined 2,496 boys in a prospective Danish-Finnish birth cohort study for cryptorchidism at birth (cryptorchid/healthy: 128/2,368) and at 3 months of age (33/2,215)....

Laparoscopic orchiopexy (LO) was used in place of open surgery in 10 patients for diagnosing cryptorchidism in our department. In this method a large abdominal incision was not given in search of intra-abdominal testes. Anorchia was diagnosed in four patients, which was shown to be bilateral in one. In one subject with ambiguous genitalia, revealing the presence of intra-abdominal gonads e...

quantitative histology of the descended testis of unilateral cryptorchid bucks was compared with testis of normal bucks to evaluate the reproductive potentials of the scrotal testis in unilateral cryptorchids, using light microscopy techniques. the contralateral scrotal testes of the unilateral cryptorchids and the testes of the normal bucks contained profiles of seminiferous epithelium and eac...

background: in most mammals, the testis is always maintained at a lower temperature than that in the abdomen, and exposure of the testis to body temperature causes degeneration of germ cells. objective: in this research, the long effect of heat exposure on sperm parameters and microstructure of mouse testis were investigated. cryptorchid mouse were induced by exposure to abdominal heat. materia...

BACKGROUND An increase in cryptorchidism has been reported in many countries. One mechanism could be low fetal testosterone production possibly secondary to altered placental human chorionic gonadotrophin (hCG) release. Our Objective was to compare hCG values from maternal blood between boys with cryptorchidism and normal boys. METHODS Total hCG and α-fetoprotein (AFP) values [12-16 weeks of ...

In animal studies, exposure to dioxins has been associated with disrupted development of the male reproductive system, including testicular maldescent. Some polychlorinated biphenyls (PCBs) have also dioxin-like effects. In addition, one previous case-control study has reported an association between congenital cryptorchidism and colostrum PCB levels. We performed a case-control study to evalua...
