you went to the clinic to do a test just because there was semen in your external genitalia?

omg you are really a noob

peace

omg

Do you know your own body? Can you differentiate the external from the internal genitalia?

You said you had no intercourse, I assume your bf only performed oral and or probably touched around your clit. Suppose that is true (that is no intercourse), his semen at most only ends up at your external genitalia. That is on the outside end of your long long birth canal!

To make a baby, sperms need to swim up all the way through the birth canal, AND then up again to the upper portion of the uterus, bordering the Fallopian tube.

Can sperms swim THAT far?

And let's not forget that the uterus is hollow. It is not filled with water or any liquid. Is it a conducive environment for semen to propagate and for sperms to swim?

No and no.

There's a reason the part that delivers spermatozoa in the male reproductive system is long.

not trying to be arrogant, im a biology student am at least better informed than the average lay person who never read further than spm

sperms have tails and they wag them around in a tadpole-like fashion, correct. the uninformed person assumes that spermatozoa indeed swims comparably to a tadpole and knows where it is headed. sperms dont even "swim to their destinations". they flow where semen flows.

u probably think that once outside the male body, they swim straight to the female eggs. there's no reason and evidence to assume that they are sentient and capable of that intelligence. they really just randomly move where semen flows.

knowing the length of the vagina, and the location of the cervical opening, if semen and spermatozoa are not inside the uterus or not in nearby position that enables it entry into the uterus by the time it exits the male system, it's the end of the road.

it doesnt even matter if they are good swimmers.

The nature of it in itself is non-probabilistic and highly deterministic. Defective rubber may get more easily torn and we statistically quantify it from their non-defective counterparts. What about objects falling to gravity? We don't even need to bother with statistics. Given preset conditions, there is no 'other' result. That's the flow of semen and Newtonian mechanics for you.

If you ask me, is it at all possible that semen flows upward and into the uterus? Definitely, given favorable preset conditions (including very unusual body movement and positioning, unusually high sperm vitality outside the uterus, and lack of backflow from the vagina). Will it happen under typical circumstances? Definitely not. The contraceptive pill has a higher likelihood - to fail. AFAIK, the vagina wasn't even designed to retain sperm, secretions will wash them all outside.

Precum (semen) from intercourse aka coitus can result in fertilization since penetration dispenses sperms closer to the cervix.
That's a very different scenario from minute amounts of semen in the external genitalia.

You seem to be talking about "pulling out" while TS said she did not have intercourse. This means, unlike coitus, semen is not delivered near the cervix.

Unless she got fingered (I'm sorry to be so crude), in which case then it is miscommunication as I assume that no intercourse = the vagina has not been breached. But then again I don't believe that fingers are efficient enough to cause pregnancy.

This is the same thing as the above. The site is talking about coitus interruptus aka pulling out in which precum is usually secreted by the penis INSIDE the vagina. In your situation, there was no intercourse, it is not comparable to what was discussed in your link.
