Can the horse sperms fertilize the woman egg?

Answer 1

No.

Answer 2

Well there are a lot of problems with this happening. Firstly it’s difficult for horse sperm to be introduced into a woman’s reproductive tract because the difference in anatomy causes some problems with any potential intercourse. Simply put the horse’s penis is not used to a woman’s vagina and it means the horse will probably not climax and just withdraws even if it can fit inside and losses interest. But in some scenarios this is possible. If the horse’s penis is smaller and compatible enough it can penetrate a woman’s vagina successfully and intercourse can happen. The horse will mount her and start probing her labia looking for her vaginal entrance, once finding it the horse will thrust his penis all the way inside her until his head hits the end of her vaginal canal close to her cervix. Once all the way in, the horse will start thrusting inside her and her vaginal walls and muscles will tighten and massage his penis as it thrusts inside her. This stimulation will eventually cause the horse to climax and most likely will not take long as her vagina will be much smaller and tighter then he is used to. When the horse climaxes he thrusts his penis all the way in and the head of the penis will engorge into a “flare” which will hold him in place. The horse’s semen will be sprayed from his penis and be deposited at the back of the woman’s vagina around her cervix. A horse’s climax is very strong and a large portion of semen will be left deep in her vagina. The flare goes away once he is done and he will withdraw. The human female reproductive tract is of course not designed for a horse’s sperm cells but it is still possible for a horse’s sperm to get quite far, especially since horse’s sperm count is much higher than humans. After being deposited around her cervix the sperm will be moved inside her cervical opening by contracting muscles. They will have to make their through her cervix in order to reach her uterus, dealing with her immune response to foreign cells, most of the sperm die in this process making it likely none will make it in. But there’s a chance for them especially if there is a lot them and horse’s sperm can find their way inside her uterus. Once they make it inside they can stay alive inside her womb for a few days but that’s all that would happen. Horses sperm lack the correct makeup to track a released human egg, thus finding their way to her Fallopian tubes is basically impossible. The horses sperm that didn’t make it into her uterus will be purged by her immune system or flushed from her vagina. The ones inside her uterus will stay in there for days wandering trying to find her egg until they all die.
