Okay, here the definitely final part of Dr. Klein's fertility research. It's Ann's fault it even exists.
Okay, I take responsibility!
(Except...what do you mean, the definitely final part of Dr. Klein's fertility research?)
Instead of running a series of tests, he was running through his lab, searching frantically for the samples.
He had opened up every yoghurt pot that anyone had ever stored in the fridge, hoping to find the most important part of his studies.
So, if you were to share Dr. Klein's fridge and if you put your pot of lunch yoghurt there, and then at lunch you grabbed it and started eating.... eh, I think I'm turning green! Am I pregnant at fifty-one, or did I just ingest a sample from the Martian Manhunter?
His search had left him able to describe new species of mold.
If you have ever shared a fridge with a bunch of other people....
“You lost the *samples*,” Superman repeated, appalled. “Tell me you’re not serious. Don’t say that I have to do it *again*.”
You already read
all the magazines, Superman?
“Well, we’ll see. But don’t even start complaining about those five days of abstinence.
It took him five days of abstinence before... he could...? Man! Those magazines must have been so uninspiring. There were no pictures of Lois in them, of course. (Couldn't he have brought Lois to that little sample-collecting room, along with Jimmy Interruptus with a yoghurt pot?)
“It’s not my fault that the stress of chasing Tempus has this effect on me.” For some reason Lois Lane was blushing behind him
*side-splitting laughter*
Superman’s sperm wasn’t immortal and he couldn’t wait another five days, weeks more likely, given the hero’s active libido.
*adores scientific lingo*
“You go searching for the samples, Superman.”
“How do I recognize them?” the hero wanted to know.
“It’s the only Kryptonian sperm around.” Dr. Klein answered impatiently. “But don’t you dare bring me the animal seed of my co-worker.
*loves the ambiguity* (Is the co-worker an animal? Or is the co-worker working on the seed from an animal?)
Dr. Klein really didn’t want to know what would happen if he needed to go to the MRT.
If he needed to go the Men's Restroom Toilet?
Dr. Klein’s heart sank. Maybe this was some kind of time-sickness after all and Lois was affected. He would have to wait even longer.
Wait for what?
“I’ve had my period.” The two Wells’ blushed, their faces almost violet.
Aaawww... *loves*
“Doesn’t mean anything, Lois,” Dr. Klein muttered, relieved. There was still hope. What Lois had considered her period might have been the implantation.
???????????????????
“There is a test-kit in the armoire over there. It’s for Chimpanzees but I’m pretty sure it works on women as well.
I'll bet!!!!
Is that Morse code for what happened when Lois used the test-kit for chimpanzees? Probably! Look what I found stuck half an inch below the screen? A yoghurt pot with something in it - uh, yucky - and this message:
----- -- -------- - ------ --- --------!
-- --- - ----? ----- ---- -- ---- ---- -- ----!!! ----!
(Translation: "I'm pregnant, Superman!
"You're pregnant? Let's go read Dr. Klein's magazines together and drink this and celebrate!!! Cheers!")
So much fun, Barbara! But isn't it a good thing that I found Dr. Klein's missing sample and the last few lines of this story?
Ann
How about a sequel? 
"Strange Pregnancy" sounds good to me - and even fits into your pattern!
