A woman saying No, Thank You.

@CatherineB22827 @mrs_ayst @stacycay Individuals with XY karyotype cannot form ovaries, so there are no such women as you describe. There are female chimeras with XY/XX karyotype who develop full female anatomy.

[Kassandra Udoff @KassandraUdoff]

@TheatreSpoonie @Twittwactivist2 @NicciHowe This woman's karyotype is not 46XY, it's 46XY/46XX/45XO. She's a female chimera. Individuals with XY karyotype can never have ovaries, they are male.

[Kassandra Udoff @KassandraUdoff]

@KaskaJessica @GauchoGregMoore @Sue0SZQ Chromosomes are not that complicated. Our system of sex determination is XX and XY. there are some chromosome abnormalities, all of which are derived from either XX or XY. No XY has produced or could ever produce ova which is what defines female.

[Kassandra Udoff @KassandraUdoff]

@voskat555555 @Darkoathz @gator_gum No. No one with XY chromosomes can have ovaries unless they also have XX (chimeras).

@TracyEdwardsMBE @rainy101 @FiLiA_charity Your stupidity and cruelty are astonishing.

[Kassandra Udoff @KassandraUdoff]

@TTExulansic @shamanspirit13 She'll also tell you that testes is what makes XX male a male.

[Kassandra Udoff @KassandraUdoff]

@catowner234 @NomadicTerra @Phlebiacclown @OakesMarianne Swyer's is still a male DSD. It causes failure of testes development

[Kassandra Udoff @KassandraUdoff]

@FCopernicium @SilentSkyZero @BumpstockBarbie This case is not an exception to Swyer's because it's not Swyer's. This woman is a female XY/XX chimera which is why she has ovaries. Swyer's patients don't have ovaries because XY simply cannot form ovarian tissues, it requires XX cells.

[Kassandra Udoff @KassandraUdoff]

@SilentSkyZero @HeyZeusMasterB @BumpstockBarbie She is XY/XX chimera. She has XX cell line in ovaries. Someone with XY chromosomes could not form ovaries.

[Kassandra Udoff @KassandraUdoff]

@shamanspirit13 @TTExulansic It's incredible that you are still spreading falsehoods about well understood DSDs. Swyer's is a male DSD that interferes with testes development. If you don't know this, stop pretending to be an expert.

[Kassandra Udoff @KassandraUdoff]

@k_salberta @jcwrightdad @atalanta44 @poz_woods The type of gonad Swyer's patients are lacking is testes, not ovaries or testes. XY cannot form ovaries. Swyer's syndrome is caused by genetic defects that disrupt testes development.

[Kassandra Udoff @KassandraUdoff]

@BobbyBr00431069 @MattWood07 @PierrePoilievre That's because Swyer's is a male DSD. Like all XY DSD's, it interferes with normal male sex development. Swyers disrupt development of testes.

[Kassandra Udoff @KassandraUdoff]

@brookelynn74 @HairyMonkeyGor1 @coomarz0 @sharrond62 Swyer's affects only males, it disrupts formation of testes.

[Kassandra Udoff @KassandraUdoff]

@HairyLeggdHarpy @DarkoDj21 @Kaijuwonk They fail to properly form testes and are sterile due to inability to produce sperm. Swyer's is a male DSD.

[Kassandra Udoff @KassandraUdoff]

@Kaijuwonk @HairyLeggdHarpy Definition of female is potential to produce ova, not "the ability to take advantage of modern reproductive technology." All XY are male, zero potential for ova. So yes, these are IVF pregnancies in male patients.

[Kassandra Udoff @KassandraUdoff]

@DarkoDj21 @Kaijuwonk @HairyLeggdHarpy Our gamete type is determined by sex chromosomes, and only by sex chromosomes. So yes, sex chromosomes are indicative of sex in humans.

[Kassandra Udoff @KassandraUdoff]

@RubyJeanette2 @David310734 @oncloud_e Of course they are all male. Swyer's is a male DSD, like all other XY DSDs - they interfere with normal male development.

[Kassandra Udoff @KassandraUdoff]

@RubyJeanette2 @David310734 @Paccyd33 @oncloud_e Swyer's syndrome only affects males. This DSDs interferes with TESTES development.

[Kassandra Udoff @KassandraUdoff]

@nicoleeo2012 @oolon Swyer's patients are not missing ovaries because that's not something they could ever develop. XY cannot form ovaries, it requires two X chromosomes.

In fact, in most Swyer's cases, degenerated testicular tissues can be observed in streak gonads. It's a male DSD.

[Kassandra Udoff @KassandraUdoff]

@oolon XY is always male, all XY DSDs are disorders of male sex development. That some of these individuals are able to take advantage of modern reorientation tech & gestate a donor pregnancy doesn't make them female.
