Dog Surgical Diseases – Infertility
1. Female dog infertility
1. Female dogs over 5 years of age or who were able to mate normally in estrus in the past will not see estrus for a long period of time (10-24 months). Or those with abnormal estrus and repeated infertility can be considered as infertility.
First, the reasons for infertility are congenital (such as hermaphroditism, underdeveloped reproductive organs, etc.), and improper feeding management (such as single feed, lack of certain essential amino acids, inorganic salts, vitamins, etc.). The bitch is overweight and thin, old and weak, and infected with certain diseases (such as brucellosis, tuberculosis, ovarian cysts, endometritis) and so on.
Second, the main manifestation is that they are not in estrus, or are repeatedly infertile in estrus, and even male dogs cannot mate with them.
Third, prevention and treatment methods: You can try pregnant horse serum, chorionic gonadotropin and estrogen for treatment. Dosage: Pregnancy horse serum (each refined product contains 400 units, 1,000 units, and 3,000 units) 25-200 units/time for dogs, subcutaneously or intramuscularly, once a day or every other day. The dosage of chorionic gonadotropin is 25-300 units, injected intramuscularly. Diethylstilbestrol is 0.2～0.5 mg/time. In addition, feeding and management conditions should be improved. If it is still unable to mate and fertilize, it should not be used for seeding.
2. Male infertility
Refers to the inability to ejaculate during mating, or the excreted semen contains no sperm, dead sperm, abnormal sperm, or low vitality, which cannot fertilize the egg.
First, there are many reasons, such as poor feed quality, lack of vitamins (mainly vitamin A and vitamin E), and insufficient exercise. Over-breeding or long-term non-breeding, male dogs are old and physically weak, reproductive organ diseases (cryptorchidism, testicular atrophy, testis and epididymitis, etc.) or infection with certain diseases, such as brucellosis, tuberculosis, endocrine disorders (androgen Insufficient etc.).
Second, the main manifestation is that male dogs have no sexual desire, and the penis of female dogs cannot be erected (impotence) when they are in heat, or they do not ejaculate after erection. Check for poor semen quality.
Third. Treatment method: The feeding and management conditions should be improved, and sufficient nutrients should be given to enhance physical fitness. To strengthen physical exercise, breeding should be moderate, to prevent too much or too little. Appropriate treatment should be given to diseases of the reproductive tract. For male dogs with a lack of libido, 10 mg of methyltestosterone (methyltestosterone) can be taken orally or 20-50 mg of testosterone propionate (testosterone propionate) can be injected intramuscularly. Male dogs that are ineffective in treatment or old and physically debilitated should be eliminated and not used for breeding.
