Swallowing Your Husband's Load Helps Prevent Pre-eclampsia And Miscarriage and Maybe Immune Rejection-based Infertilty | conceptualclarity's Blog

Neither the Bible nor legal and customary conjugal rights require that a woman suck her husband's penis much less swallow his semen. But if she's thinking about making babies she might want to give it some consideration.

Sex 'primes woman for sperm'
Regular sex with the same man may prime a woman's immune system not to reject his sperm when they try to conceive, scientists suggest.

The theory could partly explain why humans have sex even when they aren't trying for a baby.

Even a year before conception, exposure to sperm, either through intercourse or other sex acts, can have protective effects against problems ranging from infertility to miscarriages and high blood pressure during pregnancy.

Researchers from the University of Adelaide in South Australia say previous studies have suggested it could also guard against the life-threatening condition pre-eclampsia - where the mother's body rejects the placenta.

All these problems could to be linked to a failure of the mother's immune system to accept the foetus and placenta which both contain "foreign" proteins from the father's genes.

If the placenta, which supplies oxygen and nutrients from the mother's blood to the foetus, is damaged it can result in a baby that is underweight or stillborn.


The process of accepting foreign cells is called immune modulation.

After intercourse, a woman's immune system sends cells to the cervix to collect the father's foreign proteins to take back to the lymph nodes so that other immune cells can recognise them.

The Adelaide team suggests semen contains an agent which prompts the woman's immune system to accept it.

Sometimes, this process fails and women can have a severe immune response, which could be as serious as anaphylactic shock.

The agent is transforming growth factor TGF-beta.

Studies in mice showed TGF-beta switches what would usually be a hostile reaction to "foreign" sperm from the immune cells into a friendly one.

Gustaaf Dekker, one of the Adelaide researchers, said: "If there's repeated exposure to that signal then eventually when the woman conceives, her [immune] cells will say, 'we know that guy, he's been around a long time, we'll allow the pregnancy to continue.'"

He added: "We see patients that have two miscarriages, then they finally manage to get through their miscarriage period, and they have pre-eclampsia, or the placenta detaches and they have a stillbirth at 24 weeks."

Future treatment hopes

Dr Dekker also examined the impact of other sex acts on the immune system while working at the Free University of Amsterdam.

He looked at 41 pregnant women with pre-eclampsia and 44 without and found 82% of those without pre-eclampsia practised other sex acts compared with only 44% of those with the disorder.

But other doctors suggest the first group were likely to be having more sex overall.

The Adelaide team are now looking to see if men who have fathered pregnancies which have ended in miscarriages or pre-eclampsia had low TGF-beta levels in their semen.

If the theory is confirmed, women who suffer repeated miscarriages or IVF failures could be given TGF-beta along with the father's foreign proteins, possibly in a vaginal gel during intercourse

The Adelaide team even suggest understanding how a woman's immune system tolerates a foetus for nine months could lead the way to advances in the treatment of autoimmune diseases such as lupus and multiple sclerosis.

But Dr Gulam Bahadur, a consultant clinical scientist in the department of obstetrics and gynaecology at the Royal Free and University College Medical School, told BBC News Online: "The content is interesting and makes attractive reading.

"But from the scientific viewpoint one has to err on the side of caution in interpreting the many diverse and speculative points, simply because there are insufficient controls or appropriately thought out studies."

The research is published in New Scientist.

News About Pregnancy That Doesn’t Suck, But Suggests That You Do

If you’re thinking about conceiving, or certainly if you are already pregnant, there is some pretty convincing evidence that instead of just swallowing, say, folic acid, you might want to swallow something else.

Let me be delicate about this, if I can.

As far as I can tell, not only should you be having lots of oral sex with the father of your baby – even up to a year before conceiving – you should also make sure to ingest his seminal fluid. Listen to what I’m telling you: the international medical community is giving you an Rx for oral. Sure, they say frequent intercourse is good, too, but oral is better. So, if you care about having a healthy baby and not potentially unleashing what scientists call a “destructive attack on the foreign tissues” of your fetus, if you want to avoid immunological disorders during pregnancy, and I’m sure you do, get to work. Or to pleasure, depends how you feel about it.

Basically, the research says you need to be able to tolerate your baby’s foreign, paternal DNA, need to get your body accustomed to the stuff, need to cozy up to some daddy double helix for awhile so your body doesn’t reject it.

I’m no doctor, just a pregnant lady with Google, so maybe I’m horribly confused, but here is what I found excerpted online, from the Journal of Reproductive Immunology.

“While any exposure to a partner’s semen during sexual activity appears to decrease a woman’s chances for the various immunological disorders that can occur during pregnancy, immunological tolerance could be most quickly established through oral introduction and gastrointestinal absorption of semen.”

I could not make this up. Gastrointestinal absorption of semen. I know. For the man in your life, this news should not be hard to swallow. Sorry.

According to a group of Dutch researchers, “exposure to semen provides protection against developing preeclampsia.” That’s from a paper with the catchy title, “Immune Maladaptation in the Etiology of Preeclampsia: a Review of Corroborative Epidemiologic Studies.” Or you could use the subtitle: “Semen is Your Friend.”

I just can’t figure out why the whole “blue balls” thing has gotten so much traction with men, but they haven’t gotten a hold of this medical morsel.

One of my favorite pregnancy hobbies is obsessively researching dangerous pregnancy related conditions. I know, I know, I could knit, but that would be relaxing, whereas this is more congruent with my other pastimes, which include worrying about the future and raking over the past. That’s how I happened to look up preeclampsia, specifically because I interviewed actress Jane Seymour and she said she got it during one of her pregnancies, and I figured I needed a new worry charm for my shiny bracelet of maternal concerns.

First, I found this description on the Mayo Clinic’s website:

“Preeclampsia is a condition of pregnancy marked by high blood pressure and excess protein in your urine after 20 weeks of pregnancy.”

This merited a trip to Wikipedia, where I found all sorts of links to academic papers on the subject and buried therein, the dryly worded but unmistakable information about oral.

After I did some digesting about ingesting, I had to stand up from my desk chair and say to no one in particular, “Really?” If I’ve heard about a new mother eating her own placenta in a panini, if I’ve scoured sights like this for every possible detail about pregnancy, how have I missed this gem? Some of the studies I read weren’t all that new, but you’d think they would have made a bigger and more long-lasting splash.

Maybe penises need a new publicist.

Now, to be fair, the Dutch researchers do warn that with a new partner, condoms should be used to prevent sexually transmitted diseases, “However, a certain period of sperm exposure within a stable relation, when pregnancy is aimed for, is associated with a partial protection against preeclampsia,” they insist.

As far as I can tell, there seem to be myriad causes of preeclampsia and similar conditions, and it’s too complicated a medical issue for anyone, least of all me, to fully understand. Still, while some of these hypotheses have been challenged, they don’t seem to have been debunked. So to conclude, I will fall back on the medical opinion I always have about things that are either Suzanne Somers-y or reeking of placebo-ness, but obviously benign: It can’t hurt, right? At the very least, your baby will have a happy, relaxed father and parents who are intimate.

And suddenly, you wonder if the phrase “going Dutch” might acquire new meaning.

Correlation between oral sex and a low incidence of preeclampsia: a role for soluble HLA in seminal fluid?

The involvement of immune mechanisms in the aetiology of preeclampsia is often suggested. Normal pregnancy is thought to be associated with a state of tolerance to the foreign antigens of the fetus, whereas in preeclamptic women this immunological tolerance might be hampered. The present study shows that oral sex and swallowing sperm is correlated with a diminished occurrence of preeclampsia which fits in the existing idea that a paternal factor is involved in the occurrence of preeclampsia. Because pregnancy has many similarities with transplantation, we hypothesize that induction of allogeneic tolerance to the paternal HLA molecules of the fetus may be crucial. Recent data suggest that exposure, and especially oral exposure to soluble HLA (sHLA) or HLA derived peptides can lead to transplantation tolerance. Similarly, sHLA antigens, that are present in the seminal plasma, might cause tolerance in the mother to paternal antigens. In order to test whether this indeed may be the case, we investigated whether sHLA antigens are present in seminal plasma. Using a specific ELISA we detected sHLA class I molecules in seminal plasma. The level varied between individuals and was related to the level in plasma. Further studies showed that these sHLA class I molecules included classical HLA class I alleles, such as sHLA-A2, -B7, -B51, -B35 and sHLA-A9. Preliminary data show lower levels of sHLA in seminal plasma in the preeclampsia group, although not significantly different from the control group. An extension of the present study is necessary to verify this hypothesis.

Is it safe to swallow semen during pregnancy?

Gina Brown ob-gyn

There's no danger to your baby from the semen itself. As long as you're in a monogamous relationship and know that your partner is free of sexually transmitted infections (STIs), there's no risk.

If your partner is HIV-positive, it's not safe because the virus is present in semen, and you and your baby could become infected if you swallow it.

Deborah Ehrenthal ob-gyn

Yes. But remember that semen is a way to spread HIV, so you would need to be sure that your partner is free of HIV and other sexually transmitted diseases. If you're not sure, then you'll need to use a condom or avoid oral sex.

actually when i was pregnant with my son , i was about 37 weeks and i wanted to look into natural ways to induce labor since it was safe at that time, so i googles ways to induce labor and it said swallowing ejaculate is 10x more powerful than just absorbing it thru the vaginal wall, so when my husband came home i told him that, he was excited of course since i dont like doing that. so i did it and within 30 minutes my water broke.and we rushed to the hospital where my son was born an hour later. so id say its not a good idea to do so in late pregnancy unless u want to have ur baby at that time. i for one dont think that it was a coincidence either. it works. i know one thing im not doing that again lol

Wow! Well I think that too many people have too many opinions. We are all adults and should really consider that the person and persons who will continue to ask this question has feelings. Therefore, have a heart when your replying to someones personal question because we are all or have been pregnant and emotional. There is no reason to be ugly to anyone!! On a side note, I find that giving oral pleasure to my husband really turns me on in the process sometimes to the point where I have an orgasm. So bottoms up to those of you who like and those of you who don't well don't.

Hello, I am in my 6th month of pregnancy and I swallow my partners semen almost on a daily basis. Not only is there nothing wrong with doing this, but a new Study in Australia has actually proven that Swallowing your partners semen Before and Durring the pregnancy may not only help a woman conceive but may make her pregnancy safer and more successful. The Australian study found that semen contains a growth factor which helps persuade a mother's immune system to accept sperm. The Study shows that it has found evidence that regular swallowing of semen before pregnancy helps her immune system get used to her partner's sperm. The study shows that many of its 'foreign' proteins come courtesy of the father's genes so if the mother is regularly exposed to them her body is more likely to accept them.Professor Gustaaf Dekker, from the University of Adelaide, said: "If there's repeated exposure to that signal then eventually when the woman conceives, her cells will say,we know that guy.

 Oh ladies, swallowing my husband's semen is great! As a matter of fact, he tastes even better since I've been pregnant. I absolutely love every aspect of giving him oral sex and getting all of the benefits of it pregnant or not! Clearly, swallowing his semen is not killing children. Duh, if you're already pregnant, what child is going to be formed? Common sense ladies. So, swallow up!!! It taste great. Look at his face when you do it, if that doesnt turn you on, I don't know what else will!

I swallow, and I don't see anything wrong with it. To me it actually turns me on when I can actually make him feel that good. It's not like during sex, where he can take control with a different position. It gives me a sense of power and makes me want to do it more! And when you are in that moment you will do what makes you and your partner happy. To each thier own. I can understand if women don't feel comfortable with it, and know what women feel who do enjoy it.

Conceptualclarity : Many women have said that changing their husband's diet in a healthier direction made his semen more agreeable. Many wives say pineapple juice does wonders for semen taste. Makes sense since pineapple juice is one of the tastiest beverages on earth. I wonder why it's not stocked more. There are powders online sold expressly for the purpose of making semen and vaginal secretions taste better.

If you try everything and can never overcome displeasing taste, swallowing will be counterproductive. But if the taste is no worse than indifferent, I would urge fellating wives to swallow. If you are actively sucking on him as he orgasms, it will greatly intensify the orgasm. Then looking at him and smiling as you swallow his load is something many men find so titillating they say "If you find a gal who does that , she's a keeper." Well, I do advise you to rate character above willingness to swallow in your calculations, men. But you understand the point, ladies.

This is so well put together thank you.

Even if you are not going to get pregnant, and even more so after, swallowing ***** regularly can really help.

Reduce the risk of breast cancer "no less than 50%"

Live longer.

Reduce effects of aging.

...All kinds of other things.

I am divorced, but I am going to date again. I am not going to wait. And this time I am going to swallow.

***** Recipe Cookbook
Here is a *****-based Recipe cookbook that we have used in our home ..."Natural Harvest - A Collection of *****-based Recipes" It has some real nice ones for serving to guests.
***** is not only nutritious, but it also has a wonderful texture and amazing cooking properties. Like fine wine and cheeses, the taste of ***** is complex and dynamic. ***** is inexpensive to produce and is commonly available in many, if not most, homes and restaurants. Despite all of these positive qualities, ***** remains neglected as a food.
This book hopes to change that. Once you overcome any initial hesitation, you will be surprised to learn how wonderful ***** is in the kitchen. ***** is an exciting ingredient, which can give every dish you make an interesting twist. If you are a passionate cook and are not afraid to experiment with new ingredients - you will love this cook book!

sad that this kind of thing is seen as being a perk "just for the guys" in a sexual sense...if you don't like oral & swallowing, & so never do it (except of course when you wanted a kid), your husband would know that you don't enjoy it. it's almost like a chore looking at it this way...if your husband (like most men) gets turned on by oral & swallowing...wouldn't you WANT to do it anyways? turning my guy on turns me on...but maybe i'm weird!

Well, the husbands would hope that a wife aspiring to babies who swallows for medical reasons would learn to love it for the sake of pleasing him. We understand that ***** taste and women's perception of ***** taste variy hugely so not every good wife swallows. But there are no doubt a lot who have never been unselfish enough to consider seriously whether they should try to give it a go for the sake of love.
