Question

Fertilization in humans is practically feasible only if

• A. The sperms are transported into cervix within $48$ hours of release of ovum in uterus
• B. The sperms are transported into vagina just after the release of ovum in fallopian tube
• C. The ovum and sperms are transported simultaneously to ampullary-isthmi junction of fallopian tube
• D. The ovum and sperms are transported simulatenously to ampullary-isthmi junction of cervix.

Answer 1

The correct option is A The sperms are transported into cervix within $48$ hours of release of ovum in uterus

Fertilization in humans is practically feasible only if the sperms are transported into the cervix within 48 hours of the release of an ovum in the uterus. This is because the ovum is present in the fallopian tube in this duration and starts degrading after this.

So, the correct answer is 'The sperms are transported into cervix within

4848 hours of the release of the ovum in uterus'.
