Purpose : It is essential to determine normative data of testicular size and penile length in newborn infants in order to assess the development during the fetal period. In this study, we evaluated testicular volumes using ultrasonography and also measured penile lengths in Japanese newborn infants. We also examined the associations of the development of these organs with factors including placental weight and anthropometric data. Methods : One hundred and fifteen full-term male newborn infants were recruited for this study. Testicular size was measured by ultrasonography. Results : Mean testicular volumes were 187.4 mm 3 in the right testis and 185.4 mm 3 in the left testis, and there was no significant difference between the right and left testicular volumes. Right and left testicular volumes showed positive and significant correlations with body lengths and weights. Testicular volumes in the right and left sides were not significantly associated with penile lengths. In 4 groups according to gestational weeks, testicular volume increased significantly with advance of gestational weeks in the left testis. Conclusion : We determined testicular volumes using ultrasonography in Japanese newborn infants. We believe that the results for newborn infants provide important information for assessment of the development of fetal testicular volume.

Background: Nowadays, parents are paying more attention to the penis size of their children, especially obese children. Objectives: The aim of this study was to investigate the correlation between obesity, testosterone, and estradiol in prepubertal non-obese and obese children with micropenis. Methods: This case-control study was done on 58 non-obese and 86 obese micropenis children aged 8 - 13 years at Golestan Hospital, Tehran, Iran, from June 2018 to May 2020. The body mass index (BMI), testosterone and estradiol levels, stretched penile length (SPL), and the correlation between these were studied. Results: The mean age of children in non-obese and obese groups was 10.2 ± 1.34 and 10.5 ± 1.6 years, respectively. SPL in non-obese and obese subjects was 3.1 ± 1.3 and 2.9 ± 1.22 cm, respectively. SPL in both groups was significantly correlated with height and testosterone (height: r = 0.239, P = 0.009; testosterone: r = 0.344, P = 0.001) but not with BMI, weight, and estradiol. After the adjustment for age, BMI, weight, and estradiol, adjusted odds ratio with confidence interval 95% for penile length across to height and testosterone levels in non-obese group was 1.52 (0.91 - 1.83; P = 0.001) and 0.56 (0.36 - 0.98; P = 0.001), respectively and in the obese group was 1.42 (0.81 - 1.66; P = 0.001) and 0.75 (0.51 - 0.87; P = 0.001), respectively. Conclusions: Penile length is positively correlated with height and testosterone but not with weight and estradiol in non-obese and obese children. It is probably not essential and obligatory to recommend weight loss for this issue and weight loss should not be concerned by children and their parents.

“…In another study a reference value for normal SPL in 1000 full term Egyptian boys aged 1 day to 13 years was reported (18) . Other cross-sectional study on 1850 healthy Egyptian full term boys aged 0 -24 months, reported the penile length and circumference (19) . Also, a reference values for penile length in healthy term Egyptian newborn infants was reported by other studies (20,16) .…”

Background: The examination of the external genital organs is important in neonatal screening. The diagnosis of micropenis early at birth is essential as it could be the only sign of deficiency of pituitary or hypothalamic hormones. Objective: The aim of the present study is to determine the normal values of stretched penile length among preterm Egyptian newborns at different gestational ages. Patients and methods: A cross sectional study was conducted on 1000 healthy preterm male. Stretched penile length (SPL) was registered during the first 72 hours of age. Birth weight and length were also recorded. Results: In the gestational age between 32 and 36 weeks, the mean of SPL was 2.43 (SD 0.44) cm, and ranged from 1.5 to 3.8 cm. A chart was developed of penile length means, ±1 SD, ±2 SD, and ±3 SD. Conclusions:The results of the present study on Egyptian preterm neonates provide the first values for SPL (±1 SD, ± 2 SD, and ± 3 SD) at different gestational ages and could be applied on Egyptian preterm.
