all pups conceived as males????
 

My vet said that all pups are conceived as males, and some stay male while others' testicles, if you will, turn into ovaries. I know there is a technical way of wording it, but bottom line, this is what she said.

Is this really true????

Sounds really weird!! And I've NEVER heard this before.

I don't know about that, I suppose it's possible, but when they are born they are definitely male or female!

Did your vet say anything about making them "turn into females" while in the womb (you know, like food?)????.... I have two litters currently.... ALL MALES!!!

They are cute... buy hey... a female would have been nice!! ;)

There is one more male... but I couldn't upload 5 pictures....:D

Cute little guys! Can't beleive the difference in size! Lucky you to get five pups, male or female. :D

She just said that in the very early stages, they either become testicles or ovaries. No, I don't think we humans have any say-so in what sex they are. God is still in control. But I guess it just goes to show that more work goes into creating us females.

:D

Actually I read somewhere that all human babies start out as females & then some change into males.

you are right. humans fetus starts out as a female until about the 3rd-4th month and the penis and testicles emerg. now it is female by looks but the male hormone has already been presented at conception.

That's true.

Yes...this statement is true!:thumbup:

If you want females try a different stud. The male determines the gender of the litter.

Is it common for studs to have a greater precentage of one sex or the other. My male has fathered 18 pups - only three girls.

Yes. Just as with humans, the male determines the sex of the pups.

Really that is neat, See we had 2 males and 2 females our 1st litter...I never knew that...Learn something new everyday...I tell my girls this all the time! LOL! Hugs, Lee

I knew that the male determined the gender, but is it really consistent? Katie and Max had all females with their first litter. I know I have a lot of people wanting female pups, so I hope there are a least a couple next time. :)

I have a stud that throws mostly male puppies. One female had 8 puppies and all were males. Usually if there's 4 puppies, it will be 1 female and 3 males. When 5 puppies it's usually 2 females, and 3 males. He's been pretty consistent. He must have a ton of "y" sperm.

Your doc has that mixed up. There are actually 3 stages to the sex differentiation of puppies (and yes, this applies to most all mammals too -- including humans). First, from the moment of conception, the actual genetic sex is determined -- they are either XX -- female, or XY -- male. So, they are not all females to start with and not all males -- they are actually male and female depending on the presence of the Y chromosome.

The next step for the little embryo would be to develop either testes or ovaries -- these are internal initially and they may all look the same in outward appearance -- still there are little XX developing ovaries and little XY’s developing testes -- definitely male and female.

Finally, and this is where the “they all start out as females” line of thought comes from, the XY’s start to make both internal and external male “parts.” This is actually caused by both the mother’s hormones and the embryos production of hormones. If all goes right, the XY will now have the outward sex organs that readily identify him as a male.

So, no all puppies do not start out as male -- if the vet meant “appearance-wise” only, then it would be more correct to say they all start out appearing female. But in reality the XX and XY difference has been cast at conception.

In people, slow swimming sperm ((that usually lives longer))
will result in a male.
Faster swimming sperm ((but quicker to die)) will result in a
female.
I hear it is the same way for all mammals. That is how they are
now doing gender selection. The sperm for the female are also
somewhat lighter in weight. Timing proves to be everything.
I don't know who would want the job. But I learned this at
a fertility clinic.
