Is there evidence of sex by the astranauts in space flight?

Answer 1

Sex in space is distinguished mainly by the absence of gravity (unless the artificial gravity is created in the space ship) which leads to some difficulties surrounding the performing of most sexual activities. Because no certain sexual intercourse in space is known to have occurred, the topic is hotly disputed to clarify its potential impact on human beings in the isolated, confined, and hazardous environment of space.
[From Wikipedia, the free encyclopedia]

NASA does not ban sex between crewmembers.
"We depend and rely on the professionalism and good judgment of our astronauts," said NASA spokesman Ed Campion. "There is nothing specifically or formally written down about sex in space."
Still, don't expect much public commentary on sex from the space agency. NASA has historically been squeamish about the topic of sex in space; in fact, a psychologist at NASA's Johnson Space Center who studies interpersonal relationships declined, through a spokeswoman, to be interviewed for this article.
A new book written by a French astronomer, however, alleges NASA studied the feasibility of 10 sex positions in space during a space shuttle mission in 1996, though this claim has been discredited, and has been vigorously denied by NASA. (Six of the positions required the aid of an elastic belt to hold the partners together, the author writes in the book, "The Last Mission.")
The Russian Space Agency, on the other hand, is the world leader in studying the effects of crew isolation; their astronauts hold world records for time in space, and their scientists have been studying the effects of group isolation on the ground for decades. Their space station, Mir, has held mixed gender crews. Still, the Russians have made no announcements about sex and romance in space.
The only space agency that seems to be paying any attention to sexual issues in space is the European Space Agency, which published a study in 1998 that showed space flight causes a reduction in testosterone levels in male astronauts.

Answer 2

I remember reading a long time ago about Russian astranaut giving birth or flying pregnant in space; but I haven't heard of anything about sex in a space flight anywhere.

Answer 3

If you saw some of those female astronauts like Suni Williams and Shannon Lucid you wouldn't be asking that question. Unless some of the guys were into it but I doubt it. Either way it would not be something that NASA would admit too. There's no way to know but I would imagine that in their off time some of the guys have taken care of business so to speak in the privacy of their own little cubicles. That might be a messy cleanup.

Answer 4

No video has been released , in absence of gravity P*** does not go up. Suni has not given statement about periods also
Sex is earth based subject and not a high level subject

Answer 5

There is as yet no evidence of sex by the astronauts however those evil killer space monkeys have been at it for years.

Answer 6

Hi. There have been married couples in space. Now I don't know about you but I would be curious. Make that DARN curious!

Answer 7

So far no press release has been issued in this regard.
