One day, transgender Starfleet Captain James Tiberius Kirk and his civilian cisgender human husband, Steve Tucker, were in sick bay aboard the USS Enterprise. They were waiting for the results of Kirk's routine physical as well as an exam to determine why Kirk's belly was bulging. The starship's chief medical officer, Lt. Cmdr. Leonard "Bones" McCoy, MD, came into the exam room. "I have good news as to why your belly's bulging, Jim: You're twenty-six weeks pregnant. Congratulations. Other than that, everything's normal," McCoy said. "What am I having, Bones, boy or girl?" Kirk asked. "Don't know yet, Jim," McCoy said. "I hadn't planned on getting pregnant, but the news that I'm pregnant is welcome, Bones. Is it safe for me to continue to serve?" Kirk said. "Yes, Jim, it is," McCoy said. "Thanks, Bones," Kirk said, and he and Tucker embraced.
"Captain's personal log, stardate 2259.25: I have discovered that I am twenty-six weeks pregnant. Though I hadn't planned to get pregnant, I am delighted at the news that I am carrying an unborn child in my uterus. Dr. McCoy says that it is safe for me to continue to serve while pregnant, so I plan to continue serving on the Enterprise until I give birth."
In Kirk's quarters some time later, after telling the crew that he was pregnant, Kirk got on the viewscreen to his friend and commanding officer, Admiral Chris Pike. As Kirk waited for an answer, he put a hand on his belly. Seconds later, Pike answered. "Hello, Captain. Are you calling to request new options or crewmembers?" Pike said. "No, Admiral, this is about something else. Do you remember me telling you for weeks that my belly's been expanding?" Kirk said. "Yes, I do remember," Pike said. "Well, I underwent a routine physical today and while I was at it, I had Dr. McCoy look into my bulging belly," Kirk said. "Is it something bad, Captain?" Pike asked, looking worried. "No, Admiral. In fact, I'm twenty-six weeks pregnant," Kirk said. "Congratulations, Captain," Pike said, looking relieved.
On the bridge sometime later, Kirk was engaging in conversation with his Vulcan cisgender female first officer, Commander Spock. "Do you intend to continue performing your duties throughout the rest of your pregnancy, Captain? Though I have no desire for command of the Enterprise, I am willing to accept the duties of being in command of a starship," Spock said. "Yes, as a matter of fact, I intend to, Miss Spock. I've spent the past twenty-six weeks performing my duties without even knowing that I was pregnant," Kirk said.
