Teaching you about the dog's reproductive system? Nature is a wonderful being. Nature has created many lives and taught life to use breeding to reproduce the next generation. Dogs are no different from people. So let’s get to know the system that must be used to reproduce life!
Male dog
1. Testicles
teach you how to understand the dog's reproductive system? The male testicles of dogs are small, located in the vagina, one on the top and bottom, and are oval in shape. They are the human organs that cause sperm and androgens. During the reproductive period, male testicles are large, quite ductile, have abundant effects, and can produce a lot of sperm. During the period of eczema, the testicles are reduced in size and hard, and they do not have the ability to breed. The function of progesterone is to promote the growth and development of the genitals, improve and maintain all normal reproductive system theme activities. Lack of androgens will cause genital incomplete development and lack of impulse and ability to work in thematic activities of the reproductive system.
2. The ejaculation pipeline
teaches you how to understand the dog's reproductive system? Contains epididymal cysts, ejaculation tubes and urogenital system. Epididymis cysts are the site for storing sperm, and make sperm physiologically perfect and omitted, and thus have the ability to conceive egg cells. The ejaculation tube is the pipe that transports sperm. The urinary reproductive system is a safe passage for excretion of urine and men to ejaculate.
3.Articular gonad
refers to the prostate. Dogs do not have seminal vesicles and urethral bulbs. The essential substance of the prostate has the effect of giving sperm nutrients and improving sperm charm.
4. Penis
teaches you how to understand the dog's reproductive system? It is a human organ. The penis structure of dogs is relatively unique. First, it has a penis bone about 8 to 10 cm long; second, there are two very prosperous sponge bodies at the root of the genitals. During mating, sponge bodies have hematomas and are stuck in the joint of the pubic bone of the bitch, which prompts the male genitals not to be pulled out and become blocked.
Bitch
1. Uterine ovaries
teach you how to understand the dog's reproductive system? Located on the ventral side of the third or fourth intervertebral disc, it is oblong and slightly flat, and is the human organ that produces egg cells and estrogen. After estrus, a batch of egg cells will be perfected and excreted during the reproductive period. If sperm is encountered, it can be inseminated and pregnant. The effect of estrogen is to promote the growth and development of male reproductive organs in female insects and maintain the function of the reproductive system.
2. Bilateral fallopian tubes
teach you how to understand the dog's reproductive system? It is a pipeline for transporting egg cells and insemination, about 5 to 8 cm long. After the egg cells are discharged from the uterine ovary, they enter the bilateral fallopian tubes, meet the sperm here, undergo fertilization, and are transmitted to the uterus to grow and develop.
3. The uterus
is the site for babies to develop. The uterus of a dog belongs to a bicornered uterus. The uterus has a thin horn, a well-proportioned inner diameter, without bending, and the uterine corners on both sides are in the shape of a "v" shape. The uterus is short, only 1/4~1/6 of the uterine horn. Fetal babies grow and develop in the uterine horns. Because the uterine horns are relatively prosperous, they can give birth to more than a dozen dogs at the most number of litters.
4. Intravaginal
teaches you how to understand the dog's reproductive system? It is a safe channel for the output rate of human organs and fetal babies. The vagina of the dog is longer and the annular muscles are more developed.
5. Yinmen
teaches you how to understand the dog's reproductive system? It is an external reproductive organ, including vulva and Yin Emperor. There is often a periodic change during the breeding period, which is the main indicator to identify whether the estrus period is.
