Allogeneic testes transplanted into partially castrated adult medaka (Oryzias latipes) can produce donor-derived offspring by natural mating over a prolonged period

GFP-positive eggs, which indicates fertilization by sperm from the allogenic or isogenic donor testis, were produced by four of the 10 (individuals #1 ~ #4) or two of the four (individuals #5 and #6) recipient males, respectively
