Genital anomalies in newborns

Relationship between anogenital distance and testicular position in male infants with cryptorchidism with and without hypospadias

PURPOSE

Anogenital distance (AGD) may indicate hypoverilization and subsequently serve as a predictor future reproduction. In both undescended testis with and without hypospadias, our goal was to study the relationship between testicular position and AGD.

METHODS

From March 2021 to January 2023, this study was conducted on male infants with and without hypospadias and age-matched controls. Based on the infants' ages, we divided them into four. Group I: under six months, Group II: 7-12 months, Group III: between a year and eighteen months, and Group IV: 19 months up to two years of age. From the verge of the anus to the penile base, the AGD was measured. Clinical examination resulted in the classification of testicular location as high scrotal, inguinal, and non-palpable.

RESULTS

Patients with cryptorchidism had AGD means that were substantially lower than those of controls in Groups I, II, III, and IV, respectively (31 ± 2, 33 ± 3), (35.9 ± 4, 37.9 ± 5), (39.9 ± 1.2, 41 ± 1.5), and (40 ± 1.9, 44 ± 1.7). The group of patients with cryptorchidism and hypospadias differed significantly from the controls and those without hypospadias. AGD in patients with upper scrotal locations was substantially shorter. Penile length and AGD of the examined groups exhibited a positive and significant connection.

CONCLUSIONS

Shorter AGD is linked to a higher prevalence of hypospadias and cryptorchidism in male babies in comparison to normal children. The position of the undescended testis is higher in relation to a shorter AGD.

Sex difference and risk factors in burden of urogenital congenital anomalies from 1990 to 2019

Urogenital congenital anomalies (UCAs) is defined as "any live-birth with a urinary or genital condition" and affects millions of men and women worldwide. However, sex differences and related environmental risk factors in UCAs burden on a global scale have not been assessed. Using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we estimated prevalence, incidence, mortality and disability-adjusted life years (DALYs) of UCAs from 1990 to 2019 by sex, region, and socio-demographic Index (SDI) in 204 countries and territories. The disease burden of UCAs was also estimated attributable to each risk factor were estimated according to risk exposure. In 2019, UCAs caused 10,200 all-ages deaths (95% UI 7550-13,400). The combined global incidence rate was 8.38 per 1000 (95% UI 5.88-12.0) live births. The ASIR increased slightly, while the ASDR decreased from 1990 to 2019.The UCAs burden varies greatly depending on the development level and geographical location. The UCAs burden was significantly higher in men than in women, and the sex differences showed an enlarging trend. Health risks and issues, including pollution, child and maternal malnutrition, diet habits, unsafe sanitation and water source, were detected to be positively related to UCAs burden. Albeit the age-standardised prevalence, mortality, incidence, and DALYs of UCAs have decreased, they still cause a public health challenge worldwide. The high deaths and DALYs rates in low and low-middle SDI countries highlight the urgent need for improved preventive, diagnostic, and therapeutic measures. Global strategies for enhancing water safety, reducing pollution, and healthy diets are crucial steps in reducing the burden of UCAs.
