Not only do animals enjoy the deed, they also likely have orgasms, Bekoff said. They are difficult to measure directly but by watching facial expressions, body movements and muscle relaxation, many scientists have concluded that animals reach a pleasurable climax, he said.
a) Dogs and cats are not like people when it comes to sex. They don't cycle the same way and there's no evidence, behaviorally or otherwise, that sexual activity brings them any specific pleasure akin to orgasm, for example.
It seems clear that these animals are not simply going through the motions of reproduction, but are actually enjoying the physical and emotional intimacy of sexual activity.
Up until now, scientists have been aware that dolphins possess clitorises (much like all female mammals), but they weren't sure whether they experienced pleasure. Research now confirms that the animals do experience pleasure when having sex, due to their “large” clitorises.
A half man/half dog wouldn't get very far past a single cell (assuming the egg and sperm could even come together!). This is because dogs and people have very different sets of instructions in their DNA. Their genomes are simply too different to come together and make something that will live.
Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
“Two or three of the major STIs [in humans] have come from animals. We know, for example, that gonorrhoea came from cattle to humans. Syphilis also came to humans from cattle or sheep many centuries ago, possibly sexually”.
There are two varieties of chlamydia in Australian koalas, one of which, chlamydia pecorum, is almost entirely responsible for the most severe cases of the disease in the population.
He said Chlamydia pneumoniae was originally an animal pathogen that crossed the species barrier to humans and had adapted to the point where it could now be transmitted between humans. "What we think now is that Chlamydia pneumoniae originated from amphibians such as frogs," he said.
He stressed that the chances of a person catching the disease from their dog are “extremely rare”. “This is a different strain of chlamydia than the STD, and you cannot catch an STD from your dog,” he said. “The chances of catching chlamydia psittaci from your dog would be extremely slim too.
Roughly 60% of all bonobo sexual activity occurs between two or more females. While the homosexual bonding system in bonobos represents the highest frequency of homosexuality known in any primate species, homosexuality has been reported for all great apes, as well as a number of other primate species.
Another animal that enjoys having sex is the African lion. Especially male African lions show the best affiliative behavior towards their counterparts. Their two most obvious affiliative behavior or mating rituals are head rubbing and licking.
Can a Dog Impregnate a Cat? Throughout the years, there have been several speculations and theories about dogs impregnating a cat or vice versa. However, due to their huge biological differences, dogs can never impregnate a cat. With this, a dog's sperm can never fertilize a cat's egg.
Among the largest ejaculates relative to body size belongs to the boar Sus scrofa. Lüpold said that males of this boar "seem to produce ejaculates of over 50 billion sperm, which is well over 100 times a human ejaculate." European hare males also have some of the greatest sperm numbers relative to their body size.
It turns out that dogs can actually pick up on the pheromone chemical that your sweaty private parts produce, and pheromones hold a lot of information about ourselves: our diets, moods, health, even whether a female is pregnant or menstruating.
The more common strain, Chlamydia pecorum, is responsible for most of the outbreak in Queensland and cannot be transmitted to humans. The second strain, C. pneumoniae, can infect humans if, say, an infected koala were to urinate on someone, though it's unlikely.
Other STDs
Human sexually transmitted diseases ("STDs") are not carried or transmitted by animals.
If a human is bitten by a koala, then we know the infection will likely be associated with Lonepinella. The infection is similar to that seen in Pasteurella after dog- and cat-bite wounds. It can be a purulent wound infection requiring combination antibiotics and surgical drainage.
In the 1500s, this word referred to a rabbit's nest; due to the active sex lives of rabbits, the name was picked up as a slang term for brothels, a place where people engaged in regular sex and could spread the disease easily. If you had the disease, you had “clapier bubo.” This was eventually shortened to “clap.”
The most recent and deadliest STI to have crossed the barrier separating humans and animals has been HIV, which humans got from the simian version of the virus in chimpanzees. The most common STI among animals today is Brucellosis or undulant fever present in domestic livestock, dogs, cats, deer and rats.
Chlamydia, a type of sexually transmitted disease also found in humans, has hit wild koalas hard, with some wild populations seeing a 100 percent infection rate. The infectious bacteria usually aren't fatal, but they can severely impact a koala's health.
Ladybugs are known to be among the most promiscuous insects, and studies have found that STDs run rampant where they live in high densities.
Of these, 4 are currently curable: syphilis, gonorrhoea, chlamydia and trichomoniasis. The other 4 are incurable viral infections: hepatitis B, herpes simplex virus (HSV), HIV and human papillomavirus (HPV).
You can get chlamydia by having vaginal, anal, or oral sex with someone who has chlamydia. Also, you can still get chlamydia even if your sex partner does not ejaculate (cum).
