“…It then increased rapidly during the puberty. Those patterns of penile growth are similar to the penile growth reported in previous Turkey or Brazil studies (1617). However, in current study, penile size increased continuously till 13 years old.…”

There has been a great improvement in height and weight of Korean children owing to economic development over the last 25 years. This study aimed to evaluate the penile length of Korean children today and to compare it with a previous Korean study reported in 1987. The cross-sectional study was conducted with 909 Korean boys aged 0–14 years who had been brought to outpatient clinics of five tertiary hospitals (Busan, Ulsan, and Changwon) between September 2013 and May 2015. The stretched penile length (SPL) was measured and the testicular size was measured using orchidometry (mL). Student’s t-test or Mann-Whitney U test was used to compare the result of our study and the study reported in 1987. SPL of Korean children gradually increased from 4.1 ± 0.8 cm at 0-1 year old to 9.6 ± 3.0 cm at 13-14 years old, the most rapidly during the age of 13. While body weight and testicular size significantly increased from 1987 in most of age groups, there were no significant changes in SPL although there was in some age groups. Height decreased in the infants < 1 year old and increased in the children > 6 years old. With the great economic development over the last quarter century in Korea, height, body weight, and testicular size of children significantly increased but there was no significant change in SPL except penile growth pattern.

“…Micropenis was defined as penile length less than 2.5 standard deviations for age; cryptorchidism, as extra-scrotal position of the testis; and genital ambiguity were classified according to Prader's criteria5: P1 – Genitalia indistinguishable from female, except for enlarged phallus; P2 – Phallus further enlarged, labioscrotal fusion and without urogenital sinus; P3 – Phallus of penile appearance, almost total labioscrotal fusion and perineal opening of the urogenital sinus; P4 – Enlarged phallus, complete labioscrotal fusion and penoscrotal urogenital sinus opening; P5 – Phallus of penile appearance, complete labioscrotal fusion, urogenital sinus opening in the body of the phallus or balanic area 15…”

Patients with SDD predominated. Ambiguous genitalia and abnormal sexual differentiation were more frequent among infants and prepubertal individuals. Congenital adrenal hyperplasia was the most prevalent nosology. Younger patients were more common in the GUA group. Abandonment and lower frequency of birth certificate occurred in patients with ambiguous or malformed genitalia. These characteristics corroborate the literature and show the biopsychosocial impact of genitourinary anomalies.

“…Data were obtained regarding age at first evaluation, weight and length at birth, history of parental consanguinity, family history of ambiguous genitalia or infertility, severity of the ambiguous genitalia (according to Sinnecker et al classification [9] and Ahmed et al external masculinization score (EMS) [10]), penile length (in z score according to Gabrich et al [11]), levels of LH, FSH, total testosterone (T), dihydrotestosterone (DHT), T/DHT ratio, Δ4-androstenedione, and T/Δ4 ratio. LH, FSH, and Δ4-androstenedione were evaluated by chemiluminescence immunoassay, T and DHT by radioimmunoassay.…”

The aim of this study was to search for clinical and laboratorial data in 46,XY patients with ambiguous genitalia (AG) and normal testosterone (T) synthesis that could help to distinguish partial androgen insensitivity syndrome (PAIS) from 5α-reductase type 2 deficiency (5α-RD2) and from cases without molecular defects in the AR and SRD5A2 genes. Fifty-eight patients (51 families) were included. Age at first evaluation, weight and height at birth, consanguinity, familial recurrence, severity of AG, penile length, LH, FSH, T, dihydrotestosterone (DHT), Δ4-androstenedione (Δ4), and T/DHT and T/Δ4 ratios were evaluated. The AR and SRD5A2 genes were sequenced in all cases. There were 9 cases (7 families) of 5α-RD2, 10 cases (5 families) of PAIS, and 39 patients had normal molecular analysis of SRD5A2 and AR genes. Age at first evaluation, birth weight and height, and T/DHT ratio were lower in the undetermined group, while penile length was higher in this group. Consanguinity was more frequent and severity of AG was higher in 5α-RD2 patients. Familial recurrence was more frequent in PAIS patients. Birth weight and height, consanguinity, familial recurrence, severity of AG, penile length, and T/DHT ratio may help the investigation of 46,XY patients with AG and normal T synthesis.
