Question

Release of seminal fluid in the vagina of females?
A) Ejaculation
B) Implantation
C) Insemination
D) Copulation

Answer 1

Hint:Semen also remembered as seminal fluid is a natural fluid produced to hold spermatozoa. It is developed by the gonads (sexual glands) and other sexual glands of male or hermaphroditic mammals and can generate the female ovum.

Complete answer:
Before we find out the correct option let us know a little about seminal fluid. In people, the seminal fluid includes various elements besides spermatozoa: catalysts and proteolytic, as well as fructose, are components of seminal fluid which support the prolongation of spermatozoa, and give a medium through which they can drive or "swim". Semen is provided and begins from the seminal vesicle, which is seen in the pelvis.

>Option A: Ejaculation is the deliverance of seminal fluid from the penis of male. Therefore, this is an incorrect option.
>Option B: Implantation is the adjustment of the blastocyst on the uterine wall. In humans, implantation is the step of pregnancy at which the embryo adheres to the surface of the uterus. At this step of prenatal growth, the conceptus is described as a blastocyst. It is by this adhesion that the embryo acquires nutrients and oxygen from the parent to be capable of growing. Therefore, this is an incorrect option.
>Option C: Insemination is the method of discharge of seminal fluid in the vagina of the woman. If the insemination is done artificially then it is identified as artificial insemination. Therefore, this is the correct option.
>Option D: Copulation is the movement of mating among the male and female. Therefore, this is an incorrect option.

Thus, the correct answer is option (C).

Note:
i) Seminal fluid may incite ovulation, modulate immune action, provide nourishment, alter propagating-tract pH, and make mating plugs.
ii) Key roles of seminal fluid in insects hold decreasing female sexual receptivity and inciting egg-laying.
