Yes, How else would it impregnate a bitch?
yes you can. like with people you can eject a sperm into a femail dog.
produce sperm, produce testosterone
No, it is absolutely impossible for a human to get pregnant from a dog.
It isn't really any harm to humans, but it is stupid to put dog sperm in a female human.
females do not produce sperm
They can produce viable sperm as young as 4 months.
Males produce sperm from the age of puberty throughout adult life.
Most Men can and do produce sperm all their life, Unlike women, men produce live sperm continuously throughout their life. As they age, the ability to get an erection may impeded their ability to deliver it, and new research shows that it is not as lively & vigorous as men age, but most men produce sperm from Puberty throughout their lifetime.
Sperm generally starts being produced at around the age of 13 to 15. Remember this can vary depending on how fast the individual is developing.
Of course they do. Sperm is produced whole life time
Yes and entirely natural.
This will depend upon the exact state of the testicles. If both testicles are retained within the body wall, the dog will be infertile and produce no viable sperm. If only one testicle is retained within the body wall and the other has descended into the scrotum, the dog will produce viable sperm but likely have a low sperm count. If only one testicle is retained but it is outside the body wall although not in the scrotum, the dog will produce viable sperm and may have a normal sperm count. However, cryptorchidism (retained testicles) is a highly inherited condition, and it is likely that the dog would pass this defect on to his offspring. For this reason, most veterinarians and responsible breeders will advocate for the dog to be castrated and removed from the breeding pool.
Boy produce sperm "usually" between the ages of 11 and 13. There are exceptions but this is the average age.
A soon as puberty begins a boy can normally produce sperm. It is highly unusual, but not impossible, for a boy to experience the onset of puberty at age 8. as above it could happen but the odds are very low
Around your mid 12. During Puberty a boy will start to produce sperm.
