Once the ovulation day has been confirmed, fresh cooled semen insemination is 2 to 3 days or frozen semen insemination in 3 to 4 days, can be planned. Vet Clin North Am Small Anim Pract. The conception rates after intravaginal insemination with frozen-thawed semen are significantly lower when compared with the results of intrauterine insemination. Semen assessment is an important part of the evaluation of fertility in males and it should be performed as routine element of prebreeding examination. How Does Cystic Fibrosis Affect Fertility?

Antibiotics are administered for around 2 weeks after surgery. If in the AI with fresh semen the success of the procedure is strongly related to the quality of semen used and the moment for AI (Table 9), when using chilled semen both the quality of semen and the site of semen deposition are important factors for success, whilst in the AI with frozen semen, the intra-uterine semen deposition is critical (Table 10). For the in-hospital test, there are sample color changes that can help indicate approximately where in the ovulation process the dog is in currently. A decrease in the percentage of motile spermatozoa may results from temperature shock, contamination with water, urine, blood or lubricants but also from long sexual abstinence and systemic or infectious diseases, such as brucellosis. Collection of semen should be prepared in advance, and interval between collections or between the natural mating and collection, should be registered, if the male is regularly used.
