Transcervical artificial insemination in the cat.
Many studies have reported new reproductive techniques for reproduction in endangered non-domestic felids. Artificial insemination is an important tool for developing breeding programs. This manuscript reviews recent progress in feline artificial insemination, with particular emphasis on intrauterine sperm deposition. Intrauterine insemination of felids results in higher fertilization rates than intravaginal insemination, despite insemination with fewer sperm. Although surgical insemination was utilized historically, there are some reports of catheterization of the cervix of the queen. Recently, a new technique and catheter were proposed for transcervical insemination of fresh or frozen-thawed semen.
