What's the point of taking a male and a female mouse, surgically attaching them like Siamese twins -parabiosis-, connect the two circulatory systems to run the blood of the female into the male, castrate the male, transplanting a uterus into her bodyartificially impregnate the female, also insert embryos into the uterus of the male mouse and carry both pregnancies through to caesarean section for both?

It certainly does not serve the purpose of giving birth to male mice or male lambs or oxen or male specimens of other mammals. Instead, it serves the purpose of experimenting - to the great distress of these creatures - with the possibility of human male pregnancy.

This is the goal - and has been since the dawn of time: taking pregnancy, taking motherhood, finally being able to do without women except as providers of egg cells and 'pregnant blood', apparently a real elixir for the pregnant male. And it obviously serves to build a excellent business intended for trans people MtF or simply to any man who wants to experience pregnancy in order to autogynephilic fetishism.

The experiment was conducted in China by Rongjia Zhang and Yuhuan Liu, has not yet been peer-reviewed, and appears in preprint on the Biorxiv website. It is called A rat model of male pregnancy, Male pregnancy pattern in the rat. You could also simply call it Womb envythe sacred cup, the Grail of all time.

The study states among other things:

"We constructed a male rat pregnancy model with a four-step strategy: a parabiotic heterosexual pair was initially produced surgically joining a castrated male rat and a female rat. The uterus transplantation (UTx) was then performed on the male parabiont 8 weeks later. After recovery the embryos at the blastocyst stage were transplanted into the grafted uterus of the male parabiont and the native uterus of the female parabiont. Caesarean section was performed at embryonic day (ED) 21.5.

Parabiosis is an experimental model that can surgically link two animals and share their blood microenvironment through the anastomosis... to obtain the female-like microenvironment through blood exchange.. to observe the embryonic development in the uterus grafted in the male parabiont below exposure to pregnant blood.

The selected female rat was used for two different roles: as a uterus donor; as a female parabiont for heterosexual parabiosis surgery. Prior to parabiosis surgery the male's testicles, epididymis, right ventral prostate and seminal vesicles were removed.

A total of 842 embryos at the blastocyst stage were transferred to 46 heterosexual parabiotic couples at embryo day (ED) 4.5 (562 embryos transferred to female parabionts and 280 embryos transferred to male parabionts). At ED 18.5 a exploratory laparotomy to observe the development of the transferred embryos. We found that 169 (30.07%) embryos developed normally in native uteri of female parabionts at 18.5 ED, while only 27 (9.64%) embryos developed normally in grafted uteri of male parabionts.

We have therefore deduced that transplanted embryos can develop normally in uteri grafted with male parabionts only when the female parabionts conceive and provide exposure of the pregnant blood to the male parabionts. 

We constructed a model of male pregnancy in the rat and found that transplanted blastocyst-stage embryos can develop to maturity in uteri grafted with male parabionts if the male parabionts are exposed to pregnant blood from female parabionts. The success rate of the whole experiment was very low, but 10 pups could be delivered by male parabionts. by caesarean section and developed into adulthood. In addition, we found two new phenomena in our model of male pregnancy in the rat. 

Firstly, during caesarean section at ED 21.5, the following were observed abnormal stillbirths only in the grafted wombs of male parabionts. Considering that no abnormalities were found during laparotomy at ED 18.5, it was inferred that abnormal fetal death in male parabionts started late in embryonic development (approximately at ED 18.5-21.5). It remains unknown whether this phenomenon is peculiar to male pregnancy in mammals. Secondly, only embryos exposed to the pregnant blood of female parabionts can develop normally in male parabionts, suggesting that normal embryo development in male mammals relies on a mechanism that may be induced by exposure to pregnant blood rather than exposure to female blood.

Gravidanze di topi maschi per arrivare al parto maschile umano: esperimento biotech

For a part of the transgender movement and other programs for the creation of new family structures, male pregnancy is a a question of human rights. As stated in the Journal of Medical Ethics:

From the point of view of justice, there is themoral imperative to ensure equitable access to UTx [uterine transplantation].. Arguments against providing UTx to genetically XY [transgender] women that are unrelated to safety and efficacy should be carefully evaluated to address the potential discrimination against genetically XY women as a social group.

So a question of 'social justice' would legitimise this kind of research because it is considered absolutely It is unacceptable that a person who decides to make the transition from male to female - with cosmetic adaptations to her body, which in any case remains an XY body and can never be an XX body - should be denied the female experience of gestation, childbirth and motherhood.

While apparently there is no ethical problem with women being understood as providers of egg cells, wombs and even 'pregnant blood'.. In essence, freely parasitised female bodies by male bodies. It remains to be seen how and with which devices this continuous transfusion of female blood into a male body could be achieved.

Daily transfusions? Vampirization? Blood trading? Will needy women be able to think about getting pregnant in order to sell their surrogate pregnant blood, in addition to their eggs and uterus?

There is also the problem of having provided a severe suffering to defenceless animals without any justified and compelling reason other than the possible business.

As the intelligent friend who pointed out the experiment to me notes, If we were to call for the defence of animal rights, we would probably have a better chance of stopping this horror than if we were to call for the rights of women - and those of girls and children - to be taken into account, which have never been as little considered in modern times as they are in this painful end of the patriarchy.

Who cooked Adam Smith's dinner? For a RadFem economic theory, speech by Sheila Jeffreys
The traditional economy based on the 'rational' homo oeconomicus never takes into account the base of the iceberg: the huge amount of unpaid female labour without which the system simply would not stand. The necessary change does not come from the inclusion of more women in a model that is based on aggression, gambling and risk, but from a new paradigm that places the value of people, relationships and care at the centre
At a recent seminar organised by Women's Declaration International as part of its Radical Feminist Perspectives series, Sheila Jeffreys -former professor of political science at the University of Melbourne and one of the founders of the global WDI network- gave a talk on Rad Fem Economic Theory (the entire meeting can be viewed here). Jeffrey started from a text she wrote in 2010, on the heels of the global financial crisis. It was called 'Who Cooked Adam Smith's Dinner', whose thought completely omitted the [...]

Jama: when men give birth
In an incredible, recently published study, the American Medical Association's journal, one of the most important in the field, tries to give scientific backing to the idea that childbirth is not just a female experience. Because if it were exclusive, it would also be exclusionary. An operation on language in collision with reality
As we know, there are words that can no longer be used, especially in international scientific documents and studies. At the top of the list of tabooed words are all the terms that have to do with female difference understood as the exclusive possibility of giving birth to human beings, and thus: 'woman' -if biologically understood and not open to define persons not born women-, 'mother' and 'maternal', 'breast', with reference to breast-feeding, and so on. The operation on language aims to qualify [...].

The 'wheel' is not enough: help for mothers who wish to be mothers
Cots for life and the possibility of giving birth anonymously are very important. But the note left by the mother of Noemi, the baby left at the Red Cross headquarters in Bergamo, speaks of a desire that circumstances have made impracticable. What is needed is a place where, when they want to be mothers, women in difficulty can find all the support and assistance they need
The little girl left by her mother in the Cradle for Life in Bergamo - once called Ruota - has been given the name Noemi. Noemi will soon have a family and a home, and for her we wish 'all the good and happiness in the world', as her mother wished in a touching note that in just a few lines succeeds in recounting a life: 'Born this morning 3/5/2023, at home. Just me and her as in these 9 months. I can't, but [...]

Baby Fair in Milan: something to hide?
A strict and detailed code of conduct imposed on those attending Wish for a Baby, an assisted reproduction exhibition. Strictly personal badges, a ban on filming and handing out flyers, the threat of expulsion, even appropriate clothing, bag searches and scanners. And uniformed or plainclothes policemen to keep watch. Why so much caution? Isn't this just an information event on the various techniques? Perhaps there will also be talk of surrogacy, the propaganda of which is a crime in Italy? Or are they just trying to frighten off those who intend to be there to peacefully protest against the reproduction market?
Those who have registered for the Wish for a Baby fair scheduled to take place on 20-21 May in Milan have received in the last few hours this strict and detailed code of conduct that they will have to strictly adhere to if they want to be admitted to the event. But if it is, as the website explains, a 'celebration of new life', meeting 'the best fertility experts from around the world', 'attending seminars' and obtaining information, why all these [...]

Why 'asking' Schlein is a mistake
The open letter of 'one hundred feminists' to the PD secretary is based on false hopes: Elly Schlein will not change her positions on the uterus for rent. Nor on the other issues of the transhuman umbrella that the letter does not mention - starting with free gender identity - and that structure her Zan-transfeminist political identity. Is it worth adopting a begging posture?
We hope that the 'hundred feminists' who have written to Elly Schlein - and with a good part of whom we are in constant political contact - will be better off than us, who as the Network for the Inviolability of the Female Body during the primaries had asked for a meeting with the future secretary: not even a hint of a reply. Nor did we expect it, despite the long-standing acquaintance of some of us with her. We did not join the appeal of the 'hundred feminists' who intend to confront Schlein on motherhood [...].

Prefect to Mayor Sala: stop registering children of same-sex couples
The decision makes those girls and boys more equal and not unequal as we read in many ideological comments today. Starting with the equal right to the truth about one's origins enshrined in all international conventions. And to the attribution of the same rights of citizenship granted to every new born: that is why
The prefect of Milan has ordered the mayor Beppe Sala to block the transcription of birth certificates of children born by same-sex couples. For example, it will no longer be possible to fully transcribe birth certificates produced abroad - in Ukraine, Canada, California, etc. - by surrogacy, which also applies to heterosexual couples who have undertaken this practice. We radical feminists had appealed to the prefect to order Mayor Sala to respect the [...]
