Question

why testicles are not in the alimentary canal​

Answer 1

Answer:

They lie ventro-laterally below the alimentary canal, close to mid-ventral line on either side of ventral nerve cord. Each testis consists of 4-8 finger like projections/ processes, containing round cells called spermatogonia.

Answer 2

If testes don't descend, this can cause problems such as:

• Infertility. This is most common when both testes don't descend.
• Risk for testicular cancer.
• This risk increases greatly by age 30 or 40.
• Inguinal hernia.
• Testicular torsion.
