Frozen semen does require even more precise handling than fresh cooled semen. (Tsutsui, 1999, personal communication) Second, it is likely that the timing of implantation is in part related to a sequence of events regulated by the timing of the changes in serum concentrations of estrogen and progesterone. The fetal length in relation to the length of the placental girdle can be determined by ultrasound and results related to Day 40 - 42, when the fetus crown-rump length becomes longer than the placental girdle. The same ELISA progesterone kits used to monitor ovulation can be used in this regard. Frozen semen especially benefits with techniques by-passing the cervix and the cervical mucous and being deposited directly into the uterine lumen. Since that time, surgical deposition of semen into the uterus has become a routine technique used in numerous situations encountered in canine reproductive medicine. If you are early you come back and do it again! Invasion begins, Placental trophectoderm invasion of endometrium continues. Two to three weeks after the female dogs ovulation period serum progesterone concentrations reach between 10 and 80 ng/mL. Department of Biomedical Sciences, College of Veterinary Medicine, Cornell University, Ithaca, New York, USA. This extreme temperature preserves a sperm cell indefinitely, but not without stress and energy output.

A progesterone test is a diagnostic tool used to determine the timing of ovulation in female dogs. U/S detectable vesicle, Uterine vesicle visible on U/S. Ideal testing for progesterone level would include screening with the ELISA kits, but obtaining RIA progesterone numbers, will define the day of ovulation and the corresponding breeding time. Silent oestrus can be a big problem as some animals show no or hardly any signs of swelling or discharge during their season. Laboratory tests are more accurate and, because of the precise value of progesterone levels, predictions can be made more accurately.

What Does It Mean When Progesterone Levels Fall? In recently bred bitches a vaginal smear can determine if the transition from estrus to metestrus(diestrus) has occurred. Natural breeding is always a way to go, but some dog breeds like French Bulldogs require artificial insemination to become pregnant. For example, the Draminski Method evaluating electrical conduction in the vaginal canal was originally developed to assist researchers working with foxes.However, the electrical conduction in the vaginal canal reflects estrogen levels and does not indicate ovulation or the fertile window.

Precise ovarian ultrasound techniques can be used to visualize ovulation butrequire up to 3 examinations daily during the period of ovulation. The knowledge of the progesterone levels and luteinizing hormone (LH) levels during the female dog's heat can determine the time of ovulation and then the date of birth of the resulting puppies. If no motility is noted after 15 minutes, the sample is most likely non-viable. However, at the time of breeding, there is no ideal level. An overall conception rate of 67% (24/36) was obtained with a mean litter size of 6.4. While fertility is typically low with matings this late, when pregnancy does occur the gestation length is usually the same that as in other bitches, i.e., with parturition occurring at 64 - 66 days after the LH surge (and 62 - 64 days after ovulation). Vaginal cytology, a rough gauge of estrogen level, has been used by veterinarians and breeders to "pinpoint" the time of ovulation. With that cost, you are at $245 for the trip.

Your veterinarian can use a cotton tipped applicator to gently remove a few cells from the dogs vaginal vault and transfer them to a glass slide. For chilled semen inseminations, we generally arrange the AI (Artificial Insemination) once the progesterone has gone 10 to 14 ng/ml.

An egg must be a mature, secondary oocyte containing a "female" pronucleus before the "male" pronucleus of a sperm can fuse with it to complete the process of fertilization by forming the nucleus of the new one-cell embryo. Fertilization completed if already bred, Bred: 1-2 cell embryo. The drawback to these methods is that even though some energy is conserved, enough energy is used to shorten the sperm cell's life. There is a concurrent pre-partum decline in body temperature which is most readily observed with twice daily or more frequent rectal temperature measurements started several days before parturition. Delivery technique problems such as improper placement of the insemination rod, improper semen placement, or semen damage due to mishandling, have convinced many dog breeders and veterinarians that artificial inseminations are only used as a last ditch desperate measure.
