Use of silastic implants to raise plasma androgen levels in the immature baboon (Papio cynocephalus).


Two immature Papio cynocephalus baboons were implanted with silastic tubing containing testosterone (T) to obtain prolonged elevation of plasma androgen levels. Plasma radioimmunoassay indicated a thousandfold increase of T levels over baseline for three weeks. Two weeks after implant removal, plasma androgen levels were at, or below, the pre-implantation… (More)
