ABSTRACT
Birth rates in the United States have recently fallen. Birth rates per 1000 females aged 25–29 fell from 118 in 2007 to 105 in 2015. One factor may involve the vaccination against the human papillomavirus (HPV). Shortly after the vaccine was licensed, several reports of recipients experiencing primary ovarian failure emerged. This study analyzed information gathered in National Health and Nutrition Examination Survey, which represented 8 million 25-to-29-year-old women residing in the United States between 2007 and 2014. Approximately 60% of women who did not receive the HPV vaccine had been pregnant at least once, whereas only 35% of women who were exposed to the vaccine had conceived. For married women, 75% who did not receive the shot were found to conceive, while only 50% who received the vaccine had ever been pregnant. Using logistic regression to analyze the data, the probability of having been pregnant was estimated for females who received an HPV vaccine compared with females who did not receive the shot. Results suggest that females who received the HPV shot were less likely to have ever been pregnant than women in the same age group who did not receive the shot. If 100% of females in this study had received the HPV vaccine, data suggest the number of women having ever conceived would have fallen by 2 million. Further study into the influence of HPV vaccine on fertility is thus warranted.
I don’t hold you to the same standards as everybody else, Laz. (I think that’s a compliment!)
Ah, you hit it out of the park with that snark!!!
Nah. 30-50% of articles published in “prestigious science journals” cannot be reproduced. Pardon my skepticism.
I find it hard to believe that a scientific study would not take into account contraceptive use patterns when studying fertility related to a vaccine.

It is also just a bad idea to give such a thing to an entire generation without seeing long term effects - especially given that there are alternatives.
It is most likely as you posit - but not necessarily.
The cancer rate from HPV is miniscule. Not discounting it....but let's develop an alternative.
