I would have absolutely sworn that this was an episode from Star Trek: Voyager. However, I've just finished re-watching the entirety of Voyager, and the episode didn't happen! Either I managed to inadvertently skip over an episode, or it wasn't Voyager after all.

So details come in two parts:

  • Bits that I'm "certain" of having existed which aren't absolutely tied to Voyager,
  • Bits that I thought existed and do tie to Voyager specifically.

Non-Voyager Specific

Series Context: Something that involves the standard weekly cast regularly meeting aliens.

Episode Details:

  • The cast meet a new, and broadly-friendly species.
  • One (male) cast member gets particularly friendly with a female-equivalent member of the other species.
  • The "female" alien invites the male cast member back to her room/quarters/etc. and then invites them to do a shared meditation/psychic link thing, in private.
  • To the viewer it appears as a fake-out.... "Oh, they're going to have sex! Oh, no, they're just doing a some-what romantic meditation/link thing."
  • The cast and the new species go their separate ways.
  • Some time later... the male cast member starts to get weird symptoms and develops nipples on his forearm.
  • The cast go back and find the aliens.
  • It turns out that the meditation thing was (alien) sex, and the female alien assumed that they'd be biologically incompatible.
  • Shockingly, by the end of the episode everything has been sorted out, and it never comes up again.


  • The "cast" in this case would be the Voyager's crew.
  • I would have said the male cast member was either Tom Paris or Harry Kim.
  • The aliens are another species on another starship.
  • How long ago was this?

  • I'm 32; I probably saw this at least 10 years ago, but I wouldn't swear to it.

    As the answers show it's not Voyager, but I think the reason you are thinking of Voyager is because there was a Voyager Episode, "The Disease" where Harry Kim is intimate with a female member of an alien species and starts getting "symptoms".

This is the ST: Enterprise episode Unexpected.

A ship feeding off Enterprise's warp field is exposed after the crew ignites the plasma exhaust. Commander Tucker takes a trip to the ship to help them repair their warp drive. After his return to Enterprise, he learns that he is "pregnant". The nature of this event becomes a major plot device of the episode, and took the series into the realm of hard science fiction.

  • Aw man... I took too long exploring a bad lead off of tvtropes.org/pmwiki/pmwiki.php/Main/MisterSeahorse

    When Archer found out, did he say "Oh boy!"?

    "... and took the series into the realm of hard science fiction." Ummm, what?? This is Star Trek, right? I can think of a million reasons why impregnation with alien genetic material wouldn't work at all. I don't understand that claim.

    took the series into the realm of hard science fiction Uh...yeah, I don't think so. This is the same episode where the aliens gave Trip some synthesized jelly-like stuff to eat/drink claiming it was "the closest they could come to water". As though aliens had never heard of hydrogen or oxygen before...

    @BMF Teh qite may have meant "hard to believe science fiction" or something like that. Commented Jun 5, 2021 at 16:33

Unexpected Star Trek: Enterprise episode (season 1, episode 4)

Trip gets pregnant. You are correct the series is only star trek like.

  • But it's also canon star-trek. The Enterprise, Vulcans and Klingons, Andorreans, "go to warp 3.2", transporters. Overuse of time-travel. "Star-trek like" is a real misdirect in the Q. Commented Jun 5, 2021 at 16:41

    @OwenReynolds - I suspect that lucasbachmann was being snarky. In much the same way that I consider Picard and Discovery to be non-canon, but know in my heart of hearts that that just isn't true.

This sounds like VOY 5x17 "The Disease". Harry Kim experiences a biological linkage after a sex-adjacent experience on a generation ship.

    The OP has already accepted another answer, as denoted by the green check mark visible to the immediate left of that answer. As such, it's unlikely that your answer is the episode the OP had in mind. Commented Jun 6, 2021 at 18:09

    @jkingsman - I felt it was worthy of an answer (and an upvote). There's certainly some similarities between the two episodes and we know that OP has seen Voyager. He could easily be conflating them both.

    It does seem very possible that the OP saw both of these episodes, and that this contributed to his confusion over which series the episode he was looking for occurred in. But given that his description specifically mentioned the male crew member being impregnated and developing nipples on his forearms, it's all but certain that he was thinking of the Enterprise episode. The Voyager episode was certainly worth mentioning in a comment, but another user already did that yesterday. Commented Jun 6, 2021 at 19:29

    Ah, yes, I should have called out that I'd see "The Disease" and (whilst similar) it's definitely not that. FWIW I'd say that this is worth offering as a full answer. We have methods of expressing which answer is "best" and having this record here of a possible answer may help future users that were looking for this answer, with similar search keywords.
