The in-hospital test kit can indicate levels of progesterone based on color changes. Research on AI in the domestic dog, along with other reproductive technologies, proceed worldwide, particularly on sperm survival at freezing and the identification of deleterious components to spermatozoa or fertilization, providing important information for the preservation of wild canidae semen that are currently threatened or endangered. The number of spermatozoa per ejaculate also varies according to age, testicular weight, sexual activity and the size of the dog (Amann, 1986). Assisted reproductive techniques for canines: preservation of genetic material in domestic dogs. When it finishes, it will be time for you to take a pregnancy What are they?

The examination should be done on the standing animal. Intrauterine insemination of the bitch under the visual control of endoscopic equipment was first time described by Wilson (Wilson, 1993, 2001), using a rigid endoscope cysto-uretroscope of the length 29 cm with diagnostic external sheath. At ovulation, different degrees of follicular collapse can be found in the US images, and usually a clear change of the ovarian echogenicity has been detected in a large number of bitches, giving the ovary a more homogeneous aspect (Fontbonne, 2008; Fontbonne & Malandain, 2006).

Therefore, under normal conditions, the dogs ejaculate contains far more sperm cells than those needed for a seminal dose, although sometimes, especially in miniature or toy breeds, ejaculate volume and the total number of sperm cells are relatively low (<100 x106 Spz/mL). If the semen was collected after October 1, 1998 an AKC DNA profile is required. No dog is the same, but most dogs only bleed for the first 9 days of their estrus cycle.
