The most desirable of races for hosts are humans, drow, elves, githzerai, githyanki, grimlocks, gnolls, goblinoids, and orcs. Upon being implanted (through any cranial orifice), the larva then grows and consumes the host's brain, absorbing the host's physical form entirely and becoming sapient itself, a physically mature (but mentally young ...

Human reproduction naturally takes place as internal fertilization by sexual intercourse. During this process, the man inserts his erect penis into the woman's vagina and then either partner initiates rhythmic pelvic thrusts until the man achieves orgasm , which leads to ejaculation of semen containing sperm into the vaginal canal.
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism.
The pattern of constraints on female reproduction is consistent with human life-history and across all populations. A difficulty in studying human reproductive success is its high variability. [ 23 ] Every person, male or female, is different, especially when it comes to reproductive success and also fertility.
A form of asexual reproduction related to parthenogenesis is gynogenesis. Here, offspring are produced by the same mechanism as in parthenogenesis, but with the requirement that the egg merely be stimulated by the presence of sperm in order to develop. However, the sperm cell does not contribute any genetic material to the offspring.
The mechanisms of reproductive isolation are a collection of evolutionary mechanisms, behaviors and physiological processes critical for speciation.They prevent members of different species from producing offspring, or ensure that any offspring are sterile.
Furthermore, direct evidence for meiotic recombination, indicative of mating and sexual reproduction, was also found in G. intestinalis. [11] Other protists for which evidence of mating and sexual reproduction has recently been described are parasitic protozoa of the genus Leishmania, [12] Trichomonas vaginalis, [13] and acanthamoeba.
