... and remain on your back with the butt and knees elevated for twenty minutes or so. This allows time for the semen to become liquid and gives the sperm good access to the cervical os.

Now I find that absolutely amazing Brandye. Logical I suppose in that it is easier to swim through water than oil. However I did not realise that the semen would change its viscosity. Why is that? Cannot be temperature change as I would expect male and female bodies to be about 37C.

Interesting... Could it be a sort of chemical reaction, caused by the level of acidity inside the vagina of about 4,5 pH, whereas semen has 7.2- 7.8 pH (if my numbers are correct)? Or is it simply that extra fluid is added to the semen inside the vagina, making it more moist, so more liquid? Hope to be enlightened soon

OK, what you men pump into us has three constituents: semen from the vas deferens - 60% by volume; prostatic fluid from the prostate - 30% by volume and sperm from the testicles- the remaining ten percent. As an aside that is also why men who have had a vasectomy notice little or no difference in their "semen" output - only a tenth is sperm.
The purpose of the sperm is obvious: go find an egg. The purpose of the prostatic fluid is to neutralize the acidity of the vagina and the semen supplies the nutrients to sustain the sperm for a bit as well as forming a glob to most efficiently transport hundreds of millions of sperm quickly. Note that the Cowper's fluid does not figure into this. Long thought to be the acid neutralizer, it is now believed only to be a lubricant to help the glob of semen on its way out the male urethra. Upon arrival, the glob immediately begins to liquify to allow the sperm an easier fluid for swimming and also to distribute the protein to sustain the sperm. It takes about twenty minutes for the semen to become completely liquid. To the original response, if the cervix is immersed in this pool of liquid the access of sperm to the uterus and fallopian tubes, where conception actually takes place, is maximised. Women, to watch part of this happening, jack your boyfriend off into your panties (remove them first!), You will initially see the "glob" referred to and you can watch it turn to a colorless liquid. To go a bit further, set the knickers aside overnight. The semen does not stain but in the morning you can see clearly the outline of the semen and it will feel stiff, as though starched. It is otherwise undetectable. Now, put a few drops of saliva onto your finger and touch that to the stiff spot. You will note the unmistakable smell of semen. Now rinse your knickers - well. Caution: Every woman who has had semen inside her, such as your mum, has had some drain out and we can all recognize semen spots and smell! Be careful where you dry your knickers. And, rinse well. My older sister, many years ago, took the risk of going bare and pulled her knickers up, dropped them in the bin at home and mum went round the bend next morning!

Most interesting and enlightening Brandye. Thanks for that.
Now, coincidence is sometimes baffling. Last night on BBC2 was a great programme called 'Victorian Pharmacy' (which I recommend to you all!) and it was fascinating in that it looked at some of the contraceptive devices made and sold by the pharmacist of the late nineteenth century. Watching the lady make condoms out of sheep's intestine was mind-boggling. Having cleaned the intestines out of their original contents, soaked them overnight, she then disenfected them in a 'gas jar' with burning sulphur on a 'deflagrating spoon'. (I think that is the term; it is nearly 60 years since I did chemistry!). The humorous bit was when she had to cut the intestine into appropriately sized pieces and was faced with the problem of not 'insulting' the users of the condom by making it rather small. Anyway, one of the devices was a 'vaginal douche' which was intended as a hygiene aid. However, many ladies felt that this was an aid to contraception by washing out after intercourse. The presenter maintained that this action might have actually icreased the chance of pregnancy. Now why should she say that? Any comments? If you fancy watching the link here it is.They also cover making photographic paper, aspirin and toothpaste in the 1890s- good stuff. BBC iPlayer - Victorian Pharmacy: Episode 4 |

I amnot exactlycertainwhy the statement that it could increase the chances of pregnancy. Fun has a good guess and the other would be that the acidity of the vagina is reduced.
Douching is simply not a good contraceptive simply because the sperm that does the deed will likely be in the uterus before the douche is done.
