1 Zootechnical Institute, State University,
Yalelaan, Utrecht, The Netherlands The right ovary of a 10-day female embryo was transplanted into a 10-day-old capon. This
procedure, if successful, would theoretically make it possible to obtain WW hens. Sperm were obtained directly from the transplanted right gonad, because neither the ductus
deferens nor the epididymis of this gonad developed. Microscopic examination of the transplanted
right gonad revealed the destruction of the germinal epithelium, a lesion resembling those characteristic of autoimmune aspermatogenesis. The plasma was positive for anti-sperm antibodies, but
these antibodies, which attach to binding sites on the sperm head, had no influence on fertility. Normal hens were inseminated artificially with this sperm. Except for some deaths of embryos,
phenotypically normal pullets and cockerels were obtained. The chromosomal analysis of the
female offspring yielded no evidence of WW offspring.
