We reveal the challenges behind sex in space.
0:05 → 0:13
Meet Steve and Lexie, two highly experienced astronauts assigned on a three year space expedition.
0:13 → 0:19
After months of isolation in extremely close quarters and with no privacy, the inevitable happens.
0:19 → 0:24
The first sex experiment in space takes place.
0:24 → 0:29
Being weightless in space inspires Steve and Lexie to try new creative positions.
0:29 → 0:36
However, physics immediately takes over and they struggle to stick together.
0:36 → 0:41
When Steve gives Lexie the slightest push, Lexie is sent floating in the opposite direction.
0:41 → 0:45
Fortunately, Steve is prepared with elastic bands.
0:45 → 0:50
He straps himself and Lexi to the shuttle and to each other.
0:50 → 0:55
The next discovery they encounter is their lack of blood flow in zero gravity.
0:55 → 1:04
Since in space blood rises to the head and chest, Steve and Lexie find it rather difficult to get aroused below the belt.
1:04 → 1:12
It also doesn't help that when in space, all men face decreased testosterone levels that lowers their libido.
1:12 → 1:17
So even with all his excitement, Steve struggles to maintain a full erection.
1:17 → 1:24
Lexie also learns about space shrinkage as she sees that certain body parts on Steve appear smaller.
1:24 → 1:28
This is due to lower blood pressure.
1:29 → 1:36
When Steve and Lexie can finally get some astronaut on astronaut action, things get abnormally hotter and sweatier than usual.
1:37 → 1:41
Their bodies have no natural convection to carry away the heat.
1:41 → 1:47
So as they continue to perspire, they create pools of moisture that will separate and spread with every move.
1:47 → 1:52
During physical activities in space, the astronauts get exhausted quickly.
1:52 → 1:59
Due to microgravity, their heart doesn't have to pump blood as vigorously throughout the body, like it does on Earth.
1:59 → 2:08
This makes Steve and Lexie's hearts shrink over time, making the rest of their muscles weaker, which is why they're winded and fatigued.
2:08 → 2:12
The last and ultimate challenge is to conceive.
2:12 → 2:21
However, high levels of radiation in space could cause cell deformation and mutation in the bone structure of a fetus.
2:21 → 2:26
Steve and Lexie have not gone all the way just yet, but they are not giving up on this mission.
2:26 → 2:31
They plan to avoid the acrobatics and conserve energy.
2:31 → 2:38
With the help of special straps and a fun choreography, it's only a matter of time before they succeed.
2:38 → 2:45
Sex in space may be more complicated than imagined, but it's definitely quite a workout
2:45 → 2:51
and vital for future space exploration and the sake of mankind.
