Seahorses have a unique form of reproduction in that it is the male that gets pregnant after the female inserts eggs in his brood pouch, where they implant and mature into juveniles.
Most female crickets insert eggs into soil or plant stems with their long, slender ovipositors, sometimes causing serious plant damage.
After all, the doctor is an authority figure (whether male or female) who inserts various instruments into the body in order to implant "injectable fillers".
Females that insert eggs into plant tissue have an ovipositor under the tip of the abdomen, which consists of blades that slice plant tissue and guide the eggs into the slit.
(Where sex is even a question, it's a question not for humans but for monsters, as in a shot so peculiar that I actually wondered whether I had seen it correctly, in which the female MUTO inserts a nuclear warhead into a pudendum-like part of herself).
On occasion this leads to mating, in which the male curls his body around the female and inserts one of his claspers into her cloaca.
According to the published evidence, most water striders employ the "Direct coercive mating (DC)" strategy exemplified by detailed observations of A. remigis [2]; a male water strider mounts a female and inserts his genitalia forcefully into the female genital tract.
Intrigued by the conundrum, Sisneros and his colleagues caught nonreproductive females and inserted a tiny drug-releasing implant.
Females with inserts in trans were crossed to simB males, and the darker-eye offspring selected again as bearing P32 and P33 inserts in cis.
Natural mating occurred after synchronization of the females by inserting a 20 mg FGA vaginal sponge (Chronogest CR, Intervet) for 14 days, followed by injection of 300 or 400 UI PMSG (Chronogest PMSG, Intervet) just after withdrawal of the sponge.
