简介
For decades, attempts to breed elephants using artificial insemination (AI) have failed despite considerable efforts and the use of various approaches. However, recent advances in equipment technology and endocrine‐monitoring techniques have resulted in 12 elephants conceiving by AI within a 4‐year period (1998–2002). The successful AI technique employs a unique endoscope‐guided catheter and transrectal ultrasound to deliver semen into the anterior vagina or cervix, and uses the “double LH surge” (i.e., identifying the anovulatory LH (anLH) surge that predictably occurs 3 weeks before the ovulatory LH (ovLH) surge to time insemination. This study describes the 6‐year collaboration between the National Zoological Park (NZP) and the Institute for Zoo Biology and Wildlife Research (IZW), Berlin, Germany, that led to the refinement of this AI technique and subsequent production of an Asian elephant calf …
