To determine the effect of tobacco consumption on paternity rates in men with a history of cryptorchidism. To compare the paternity rates between formerly unilateral, bilateral cryptorchid smokers, and nonsmokers.A retrospective cohort study of 153 men who UNASSIGNED
Cryptorchidism is the most frequent congenital malformation in boys and is associated with low sperm count, infertility and testicular cancer. Unhealthy maternal lifestyle during pregnancy such as smoking, high prepregnancy body mass index (BMI) as well as alcohol and caffeine intake may
BACKGROUND
Cryptorchidism is a common and prevalent condition in patients with Down syndrome. Environmental factors, such as smoking, can be associated with malformations during fetal development. The study of the prevalence of cryptorchidism and its association with parental tobacco use in Down
BACKGROUND
Risk factors for congenital cryptorchidism were investigated in a prospective birth cohort study in Denmark and Finland from 1997 to 2001.
RESULTS
In total, 2,496 boys were examined for cryptorchidism at birth (cryptorchid/healthy: 128/2,368) and three months old (33/2,215). Information
Persistent health disparities are a major contributor to disproportionate burden of cancer for some populations. Health disparities in cancer incidence and mortality may reflect differences in exposures to risk factors early in life. Understanding the distribution of exposures to early life risk and
Testicular cancer is the most common malignancy in men 20 to 35 years of age and has an annual incidence of four per 100,000. If diagnosed early, the cure rate is nearly 99 percent. Risk factors for testicular cancer include cryptorchidism (i.e., undescended testicles), family history, infertility,
BACKGROUND
Disorders of the male reproductive system are increasing in prevalence. The term testicular dysgenesis syndrome emphasizes the importance of developmental influences on the aetiology of conditions including cryptorchidism, testicular germ cell cancer and reduced spermatogenesis. Men whose
A study of semen analysis and testicular biopsy was done in 50 infertile males. Semen analysis and testicular biopsy form important screening tools. Commonest age group affected was 21-40 years with sterility of 2-6 years duration. Smoking or tobacco chewing for longer periods may change semen
Male reproductive disorders that are of interest from an environmental point of view include sexual dysfunction, infertility, cryptorchidism, hypospadias and testicular cancer. Several reports suggest declining sperm counts and increase of these reproductive disorders in some areas during some time
The prevalence of male reproductive disorders, such as testicular cancer and impaired semen quality, is increasing in many, albeit not all, countries. These disorders are aetiologically linked with congenital cryptorchidism and hypospadias by common factors leading to perinatal disruption of normal
Reproductive pathology in the male represents about 20% of infertility cases. Male infertility may be attributed to a number of causes, including genetic and congenital abnormalities, infection, multisystemic diseases, varicocele, and others; however, a significant number of cases are idiopathic.
