Testicle sized and polyamory

Just a little thing:

The competition to elect New Zealand’s bird of the year has intensified with a vote-rigging scandal and an adult toy store endorsing a small, polyamorous bird with unusually large genitals.

Fair enough. And the large testicle size does seem to be linked to the polyamory bit. Whether of the polygyny type – produce enough to get the job done – or the polyandry – there’s a competition going on there.

The relative size of testes is often influenced by mating systems.[42] Testicular size as a proportion of body weight varies widely. In the mammalian kingdom, there is a tendency for testicular size to correspond with multiple mates (e.g., harems, polygamy). Production of testicular output sperm and spermatic fluid is also larger in polygamous animals, possibly a spermatogenic competition for survival. The testes of the right whale are likely to be the largest of any animal, each weighing around 500 kg (1,100 lb).[43]

Among the Hominidae, gorillas have little female promiscuity and sperm competition and the testes are small compared to body weight (0.03%). Chimpanzees have high promiscuity and large testes compared to body weight (0.3%). Human testicular size falls between these extremes (0.08%).

Humans appear to be slightly polyamorous but not very much.

  1. I’m picturing a caption of a lady gorilla, as a silverback broods in the background, reading the Nature headline “Gorilla’s not promiscuous” with a thought bubble. “chance’d be a fine thing”.

  2. There’s a difference between being sexually promiscuous and being polyamorous.

    The BBC often have articles in polyamorous set-ups. There is usually a chubby woman with blue hair living with two gingery blokes with wispy beards and lots of piercings. They mainly seem to live in Wales

  3. This brings back memories of the Danube Steam Ship Company captain with his cap and other appurtenances.

  4. An alleged vote rigging scandal, together with comments about unusually large testicles?
    At first, I thought there would be a link to the American presidential elections. What a let down. Has anyone compared Don’s and Joe’s by the way? It could affect the result.

  5. The book “Sperm Wars” may be a little out of date now but it’s still pretty eye-popping. Devious little bastards, those spermatazoa.

  6. “Human testicular size falls between these extremes (0.08% of body weight).”

    Quite amazing isn’t it? Considering so many blokes do most of their thinking with them.

  7. Dennis, Neither Polyamorous Nor Well Endowed

    New Zealand seems to have a bit too much time on its hands.

    I thought they already elected that Jacinda bird?

  9. Most bird nuts are internal*. In fact, I can’t think of a North American bird that has external nuts.

    Being a biologist, I wonder how aerodynamic this little chickadee’s nads are.

    *Being internal, we don’t see them. Hence, there could be some bird that is 50% balls, and we just don’t know it.
