Abstract
During ontogenesis an imbalance is observable in the development of the skeletal
and vascular systems. By means of anatomical and radiological methods the
gonadal veins were studied in relation to the vertebral column in 60 human
foetuses of both sexes aged from 4 to 6 months of prenatal life. In male foetuses
aged 4–5 months the origin of the gonadal veins projected onto the sacral
apex (r1 = 0.95, r3 = 0.85), and in 6th month they extended below the vertebral
column (r1’ = 0.80, r3’ = 0.90). In female foetuses the origin of the gonadal
veins in the 4th month projected symmetrically onto S1 (r5 = 0.70, r7 = 0.70). In
the 5th month of intrauterine life the origin of the left ovarian vein was found at
S2 (r7’ = 0.80) and the origin of the right one at S1–S2 (r5’ = 0.80). In the
6th month the origin of the left ovarian vein was located at S3 (r7’ = 0.80) and
the right one at S2–S3 (r5’’ = 0.90). The skeletopic analysis of the origin of the
gonadal veins demonstrated gender (the origin was higher in females) and syntopic
(the origin was higher on the right side) differences (p ≤ 0.05). In foetuses
of both sexes aged 4 months of prenatal life the termination of the left gonadal
veins projected onto Th12–L1 (r4 = 0.85, r8 = 0.80) and in foetuses aged
5–6 months it projected onto L1–L2 (r4’ = 0.90, r8’ = 0.95). In both sexes the
termination of the gonadal veins on the right side projected constantly onto L2
(r2 = 0.90, r6 = 0.95) from the 4th to the 6th month of intrauterine life. The skeletopic
analysis of the termination of the gonadal veins showed syntopic dimorphism
(p ≤ 0.05) without gender differences (p > 0.05). On the right side the
termination of the gonadal (testicular and ovarian) veins projected constantly
onto L2. On the left side the termination of the left gonadal (testicular and
ovarian) veins apparently descended by one vertebra (pseudodescensus).
