and reading why several women trying for babies that were still actively having sex with their dogs and were unable to conceive until they stopped for about 2-3 weeks.
There are a number of mechanisms keeping a dog's sperm from penetrating a woman's egg, such as the mitotic checkpoint which requires all chromosomes to be correctly paired, but this also often fails amongst humans (hence people with downs syndrome).
However, due to the factors listed below, dog sperm often floods a woman's womb, inundating her fertile egg, with a few penetrating through her egg's defenses and impregnating her egg, albeit for only a short time before the chromosome mismatch causes it to fail and the egg becomes infertile.
1. Dog sperm appears to be faster and stronger than a man's sperm as a dog's uterine track is harsher to sperm than a woman's. So while a man's sperm can only last 3 days in a woman's womb, a dog's sperm can last up to 9 days while it seeks to impregnate her egg.

2. Dog sperm is shaped remarkably similar to human sperm and passes many of the same mechanical and physical checks that human sperm does

3. The average volume of human ejaculate is 1.5-5 ml

4. A healthy man can release up to 250 million sperm in an orgasm

5. The shape and pressure of the dogs cock forces much of the semen directly on to the woman’s cervix. Since dog sperm has a much lower viscosity than human sperm, meaning that it is much more liquid and less dense, dog sperm has a much easier time passing through the cervix to impregnate its mate. Much of a dog's sperm is forced into it's mate's womb over the roughly 30 minutes mating session

6. Köpekler genellikle eşleriyle 30-45 dakika çiftleşirler. Üyelerinin büyüklüğü, vajinanın içindeki tüm spermi sıkıca tutan düğümün işlevi, köpeğin penisinin doğrudan servikse doğru itme şekli, bir köpeğin 30-45 dakikalık boşalması sırasında büyük miktarda sperm atılması ve köpeğin sperminin ince doğası nedeniyle, genellikle çok miktarda köpek spermi doğrudan rahme girer - bir kadının rahminin içindeki sperm selinin yumurtalarını ezmesine ve birkaç sperm yumurtanın savunmasına nüfuz etmeyi ve kromozom uyumsuzluğunun yumurtanın kısır hale gelmesine neden olmadan önce kadının yumurtasını kısa bir süre emdirmeyi başarırken, onları tamamen kaplamaya yol açar

Bir kadın cums onu serviks flexes her zaman açık ve eşinin dick kafa karşı bastırır, onun cum kadar kucaklamak isteyen. Bir kadın köpeğine 30-45 dakika boyunca ve yukarıdaki tüm faktörlere bağlı olduğu için, serviksi, dönem boyunca muazzam miktarda cum atacak ve daha fazla köpek sperminin rahmini su basmasına ve yumurtalarını boğmasına neden olacak ve onları kısa bir süre emdirecektir.

You notice how much their cervixes opens when they're cumming, especially the second one, and even after orgasm how open they stay? It's pretty fucking hot to think about the sheer amount of doggy cum that gets pumped directly into a woman's womb whenever a woman is bred by her dog.
In effect, a dog's sperm inundates a woman's egg, coating it in sperm and ultimately often overwhelming her egg's defenses for a short time before her egg is rendered infertile by the mismatch.

love to hear more about women's experiences here who have tried getting pregnant with their partner while still regularly zoo-active.
