A Video for Klinefelter's Syndrome.
Did it for Biology, hope it's informative.
Made with Adobe After Effects.
Ignore the name "Robert Carlos" Was too lazy to wait 3 hours to republish just to take out his name.

    great information shared

    well done to all the posters

  • @zdunmar Of the fertility study I am referring to 50% of the XXY participants had some sperms in their ejaculate. Obviously then 50% had no sperms and I have never had any sperm production at all in my ejaculate. However, you must be aware of ICSI, when even immature sperms a can be extracted form XXY's testes and used in IVF? This is excellent news. When candidates are selected for ICSI they have to stop TRT as exogenous testosterone prevents the formation of sperm.

  • @ajt1012 Testosterone will in fact reduce fertility as sperms need to be saturated in testosterone to develop properly. Men with KS have defective testes to start with. Testes only get as big as they do in men without KS because of testosterone production.Men with KS have testes that can't expand from increased instructions to produce testosterone as their seminiferous tubules retard the growth of their leydig cells, the cells that produce testosterone. We take TRT to replace what we don't make.

  • @ajt1012 If time is of any relevance, I was diagnosed at 16.5 and treated since 17 for Klinefelter's syndrome. I have now been taking testosterone for 35 years. Zdunmar has described his circumstances. That they are not the same as mine can hardly be descried as unusual, after all he did go for 32 years without a diagnosis, whereas I went for half that time. He developed osteoporosis at a very young age because he was not treated. Testosterone is not designed to improve fertility. (next)

  • @zdunmar I must check your channel out for updated information that you make available, or you make sure you're kept up to date, I make sure as many people as possible are kept up to date, and I'm ChromosomesXXY. The matters I report on from statistical analysis are all true, but if you can come up with anything that is untrue in my videos or text statements that are untrue, and you have the evidence to show they're untrue, I'll be more than happy to delete the videos and amend my statements.

  • @XXYforLIFE

    That's pretty interesting!

  • @ajt1012 I used to own ChromosomesXXY but it got 2 red flags in quick succession and I closed it down. But anyway, as time has gone by I have learned a great deal more accurate information. The LD's we CAN get are associated wit the additional X material, not KS, which is in fact just a collection of symptoms of the disease seminiferous tubule dysgenesis. And we have no more complete X's active in our cells than any other person, just 1. Look up X inactivation for more information.

  • @Aleksei5055 Some geneticists call XXY a syndrome, but 'syndrome' means "a collection of symptoms indicative of disease." So those geneticists are mistaken. Chromosomes that are usual are not indicative of disease, and 1 of something cannot be called a 'collection.' Klinefelter's syndrome is a collection of symptoms, such as female pattern pubic hair, fat distribution, sparse facial & body hair, low testosterone. BTW All males when they start puberty have female pattern pubic hair, the clue.

  • @Aleksei5055 The condition Klinefelter's syndrome isn't really as disease at all. It is the symptoms of a disease, and that disease is called Seminiferous Tubule Dysgenesis.The seminiferous tubules are the structures in the testes where sperm develop. As they are defectively formed, that's what 'dysgenesis' means, the testes are small and firm. If an XXY man does not have small firm testes he does not have Klinefelter's syndrome. KS and XXY are not synonymous. This video fails to note that fact.

  • @Aleksei5055 This the way it works, XXY CAN have none of or all of the conditions mentioned in this video. It depends on many other factors as to what their difficulties will be for each individual. The ONLY universal fact affecting all XXY's is that they are XXY. Looking at just 1 disease they can get, the disease they're all assumed to have, Klinefelter's syndrome, the ONLY universal characteristic is small firm testes. Osteoporosis only comes about in the UNTREATED KS men.
