Cryptorchidism is the absence of at least one testis in the scrotum. The incidence of cryptorchidism is high and almost 3% of boys in the western countries are operated on for this condition. Abnormalities in the hypothalamo-pituitary-testicular axis may result in cryptorchidism, and cryptorchidism is nearly almost present in individuals with a testis and(More)
UNLABELLED Undescended testis is a common finding in boys, and the majority of cases have no discernible aetiology. There are unexplained geographical differences and temporal trends in its prevalence. Cryptorchidism, especially bilateral, is associated with impaired spermatogenesis and endocrine function and increases the risk of testicular cancer. There(More)
PURPOSE The fertility potential of boys with cryptorchidism may be related to the number of adult dark spermatogonia per tubular transverse section in testicular biopsies taken at orchiopexy. Placental-like alkaline phosphatase positive gonocytes in testes within year 1 of life indicate preserved ability for germ cell transformation. We related these(More)
AIM To reach consensus among specialists from the Nordic countries on the present state-of-the-art in treatment of undescended testicles. METHODS A group of specialists in testicular physiology, paediatric surgery/urology, endocrinology, andrology, pathology and anaesthesiology from all the Nordic countries met for two days. Before the meeting, reviews of(More)
It has been hypothesized that poor semen quality, testis cancer, undescended testis, and hypospadias are symptoms of one underlying entity--the testicular dysgenesis syndrome--leading to increasing male fertility impairment. Though testicular cancer has increased in many Western countries during the past 40 years, hypospadias rates have not changed with(More)
PURPOSE Considerable controversy exists regarding the recently published high prevalence of cryptorchidism and the actual orchiopexy rate in Denmark. Therefore, we carried out another prevalence study. MATERIALS AND METHODS The study population included 1,094 consecutive males delivered alive at Glostrup University Hospital during 2002, with a 4-year(More)
A total of 91 boys underwent bilateral orchiopexy with testicular biopsy. The percentage of tubular transverse sections containing spermatogonia, the fertility index (FI) and the number of spermatogonia per tubular transverse section (S/T) were measured and expressed as a percentage of the minimum normal value (FI% and S/T%, respectively). The maximum and(More)
OBJECTIVE Antenatal ultrasound diagnosed anomalies of the kidney and urinary tract (AUDAKUT) are reported in 0.3%-5% on prenatal ultrasound (US) and 0.3%-4.5% on postnatal US. The anterior-posterior diameter of the renal pelvis (APD) is an essential measurement. Series with low threshold values of APD prenatally and postnatally will include healthy infants.(More)
OBJECTIVE The objective of the study was to assess physical activity intervention assessed by a pedometer with or without dietary intervention on gestational weight gain (GWG) in obese pregnant women by comparing with a control group. STUDY DESIGN This study was a randomized controlled trial of 425 obese pregnant women comparing 3 groups: (1) PA plus D,(More)
BACKGROUND A long-term culture system of testicular biopsies from boys with undescended testes was established to evaluate the effect of gonadotrophins on germ cell survival and growth. METHODS Biopsies from 25 boys with cryptorchidism, aged 1.1-9.9 years, were obtained at the time of surgery. Each biopsy was subdivided into fragments and cultured for 1(More)
