The phrase "copulation without" is grammatically correct and usable in written English
It can be used when discussing sexual activity without the act of copulation or sexual intercourse. Example: The study found that some species of animals engage in copulation without penetrating each other, which challenges traditional ideas of reproduction.
Females called more often when ejaculation occurred, and these calls were longer than the calls given during copulations without ejaculation.
However, males re-use their mating organs and by experimentally mating males to many females, we show that the sperm supply is divided between copulations without reloading the pedipalps.
The big-mouthed female spiders have a nasty habit of cannibalizing potential mates before copulation, and without sperm to fertilize their eggs, all their hard-won superfecundity could go to waste.
Primates are unusual in that many females display sexual signals, such as sex skin swellings/colorations and copulation calls, without any sex role reversal.
While copulation is possible without a gift, the short mating and insertion durations make mating without a gift unsuccessful.
It was concluded that the permanent presence of male without copulation with estrus-synchronized does hastened estrus onset, reduced estrus duration, and decreased the interval time from CIDR removal to ovulation without modification of ovulation time and number of ovulations in Boer goats.
The objectives of the present study were to assess the effect of permanent contact of teasers without copulation on the interval from controlled internal drug release (CIDR) removal to estrus onset, estrus duration, ovulation time, number of ovulations, and interval from CIDR removal to ovulation time on estrus-synchronized Boer goats.
Although some urodelan families reproduce by external fertilization, most extant salamanders have internal fertilization, in which the female picks up the male spermatophore with her cloaca without copulation.
First, the production of (diploid parthenogenetic) offspring without copulation could have been achieved through the rare production of offspring from unfertilised eggs, which has been observed in many other insect species [ 8, 18].
In the copepods (e.g., sea lice, Cyclops) and the amphipods (e.g., beach fleas), the sexes are mostly separate, copulation is brief and without elaboration, and the female of both groups broods the fertilized eggs.
