Figure 2 – The figure shows the steps of testicular migration during the human fetal period. A) The figure shows a male fetus with 15 weeks post-conception with both testes situated in the abdomen. The abdominal wall was dissected to show the position of the testis (T) above the internal ring (arrowhead); B) The figure shows a male fetus with 18 weeks post-conception. The abdominal wall was dissected and we can observe the right testis (T) just above the internal ring (IR) and the distal insertion of the gubernaculum testis (G); C) Photomicrography of the same fetuses of Figure 2B showing the proximal insertion of gubernaculum testis. We can observe that the gubernaculum is attached to the testis. Masson’s trichrome X100; and D) The figure shows a male fetus with 30WPC with both testes situated in the scrotum, we can observe the left testis (T) in scrotal position.(page 38)
