Fertilisation in humans is practically feasible only if:
Correct answer: D. the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the Fallopian tube.
- A. the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the cervix
- B. the sperms are transported into cervix within 48 hrs of release of ovum in uterus
- C. the sperms are transported into vagina just after the release of ovum in Fallopian tube
- D. the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the Fallopian tube.
Explanation
The fusion of a haploid male gamete (sperm) and a haploid female gamete (ovum) to form a diploid zygote is called fertilisation. In human beings, it takes place in the ampullary isthmic junction of the oviduct (Fallopian tube).

About Reproduction
Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
