gonad

Ohta is an expert in anesthetizing newborn mice using ice, performing intricate surgery on them, and injecting cells into the animals’ miniature gonads.

Researchers could then collect the model embryo’s gonads, which could be further matured, either in the lab or via transplant into the woman’s body, to produce youthful eggs.

While this male’s death was a tragedy, there is a chance his genes may live on in future offspring thanks to the quick report of his death and the retrieval, shipping and processing of his gonads.

This fact led Cuvier erroneously to the belief that a duct existed leading from the gonad to this papilla.

The essential reproductive organ or gonad consists of both ovarian and testicular cells (see fig. 42).

It seems that the posterior nephridia are mainly gonad ducts, and the gonads are developed in close association with the funnels.

To this category will belong the oviducts in Teleostean fishes and probably the gonad ducts in several groups of invertebrates.

In some forms the kidney is closely associated with the gonad, and seems to coperate with the latter in the generative functions.
