Question

Fertilisation takes place in the
A. Follicle
B. Oviduct
C. Uterus
D. Vestibule

Answer 1

We know that menstrual cycles get the woman’s body half-ready so that the processes of human fertilization can resume. In the process of fertilization, one sperm is fused with an ovum. The sequence in general begins with the ejaculation during copulation and then it follows to the process of ovulation and lastly it finishes with fertilization.

Complete answer:
1. Ovarian follicles are some sort of small sacs which are filled with fluid as found in women's ovaries. These contain egg cells which are released during ovulation.
2. The fertilization essentially takes place in the oviduct. It is also called a fallopian tube. It generally occurred in the upper portion of the uterus. In case of some inflammatory disease in the pelvic region, the fertilization can happen in the location which is outside of the reproductive tract.
3. After reaching over the stage of ovulation, the egg is released into the channels of oviduct where fertilization takes place.
4. In order to implant themselves into the side of the uterus, the eggs start to divide into cells within 1 day after they are fertilized. Usually they remain in the oviduct up to 4 days.
5. It has been found that approximately after 3 weeks, the first nerve cell of the offspring is going to emerge.
6. The main action of the uterus is to nourish the developing foetus prior its birth.
7. The female vagina opens where the external genitalia lie and this is called vestibules.
8. So we can say that it is oviduct where fertilization is taking place.

Hence the correct answer is option ‘B’.

Note: After egg is fertilized, no other sperm is able to penetrate again into that egg. When the fertilization occurs, the genes of the offspring are also determined by the same time. When fertilization is over, the fertilized cell which is called zygote passes through the fallopian tube or oviduct and goes into the uterus.
