Trump demanded more babies, but disbanded a gonad specialist.

Tens of thousands of young women choose to freeze eggs every year. The number is increasing as more Americans postpone their fertility. But there are many unknown people: What are the best donors for freezing? What is the success rate? And critical: How long does the frozen egg last? Answer of these questions can be more difficult to find. The Trump administration abolished the federal research…

Which bits for Bob?

Anonymous said to @ask-drferox: How would one tell the difference, on examination, between an undescended testicle and an ovary in a hermaphroditic cat? Is it obvious?

From the outside of the cat, you often have no clue what the gonads are unless you’re going to go ahead with an ultrasound scan, and the situations in which you’d do this are pretty rare. You might have an ultrasound performed in an infertility investigation, but honestly it’s pretty rare as if a tom doesn’t have both testicles present and correct where they should be on the outside, he shouldn’t be bred from. Cryptorchidism is genetic.

Most of the time an intersex animal (and i encourage you to use the term intersex, as it’s more current, more polite, and trying to classify individuals as hermaphrodites/pseudo-hermaphrodites/chimeras/masculinised-female etc is confusing, academic at best, and something of a waste of time in clinical practice) is discovered at the time of desexing.

If the gonad is in the scrotum, it’s a almost certainly a testicle. It might not be a completely normal testicle, but it still counts for the remainder of its brief existence. Likewise with gonads located in the groin or inguinal ring, as ovaries don’t tend to move that much.

A gonad which resided inside the abdomen is usually an ovary, but occasional intersex individuals will have internal testicles, or nothing, or one of each, or a pair of ovo-testes.

When you actually have the organ within your fingers, it’s not that hard to tell what you’ve got. Testes actually have a fairly defined structure with central fibrous tissue that radiates outwards, like the inside of a kiwi fruit. The ovaries are not as structured but are kind of grape-like when they get follicles.

So the normal organs do look very different to each other. The abnormal organs still are usually recognizable by how they are structured, just kind of small and empty.

If you really want to know you can send the gonad you’re removing away for histopathology, but that’s really just academic. You’re removing the gonads anyway, the animal can’t breed, so it gets a little footnote in its medical file and gets on with its life.

Abstract

This study used Littoraria scabra as a research model of reproductive strategy and attempted to understand how the species optimize their survival in mangrove area. It was aimed at investigating the reproductive strategy of ovoviviparous L. scabra in order to maintain their survival in mangrove ecosystem. Reproductive strategy observations of L. scabra were done by looking at mating, gonad maturity index, and sex ratio. Results showed that the reproductive strategy of L. scabra was as follows: a) there were 64.58% of mating pairs on the stem of S. ovata and b) sex ratio was globally significant different, but it was generally nonsignificant on monthly basis. Specific strategy of ovoviviparous species L. scabra with reproductive patterns, i.e mating, gonad maturity, and sex ratio was to optimize their reproductive success in extreme three-dimensional mangrove habitat. This study concluded that the reproductive strategy uniqueness of male L. scabra possessed fertilized eggs and very rare brooding system in male body and quickly released larvae.

Life Of Others (Post#20) : Pinctada Maxima Oyster

Photos of the day are all about Pinctada Maxima Oyster. During the visit in Willie Creek Pearl Farm, I had a chance to see Pinctada Maxima Oyster, where one was shown in our group, fresh from Willie Creek Pearl Farm and one of the facilitator in pearl farm tour showed us and explained to us how pearl is cultured. In the process of seeding the…
