Reproduction and Development in Frog -

  • Frogs have well-organised male and female reproductive systems.

Male Reproductive System

  • Male reproductive organs consist of a pair of yellowish ovoid testes which are found adhered to the upper part of kidneys by a double fold of peritoneum called mesorchium.
  • Vasa efferentia are 10-12 in number that arises from testes. 
  • They enter the kidneys on their side and open into Bidder’s canal. 
  • Bidder's canal is present inside the kidney of the frog. It receives sperms from testes via a number of vasa efferentia.
  • Vasa efferentia communicates with the urinogenital duct that comes out of the kidneys and opens into the cloaca. 
  • The cloaca is a small, median chamber that is used to pass faecal matter, urine and sperms to the exterior.

 

 

Bidder’s canal is present in the kidney of male frog. It is helpful in the transfer of the sperms from the vasa efferentia to water.
