Question

Given below are certain situations. Analyze and describe its possible impact on a person:

a) Testes of a male boy are not able to descend into scrotum during his embryonic development.

b) Vas deferens of a man is plugged.

c) Prostate and seminal vesicles are not functional.

d) Egg is not fertilised in a human female.

e) Placenta does not attach to the uterus optimally.

Answer 1

(a) Sperm formation will be adversely affected because it requires a lower temperature than the body temperature.

(b) Vas deferens is a passage for transfer of sperms, so sperms will not be transferred further.

(c) When prostate and seminal vesicles are not functional, they will not add secretions for nourishment and medium for the transport of sperms.

(d) When an egg is not fertilised in a human female, it lives for about one day. Then, the thickened lining of the uterus breaks leading to discharge of blood and mucus along with the unfertilised egg. This is called menstruation.

(e) Nutrition and oxygen will not be provided to the growing embryo affecting its growth, which could have serious implications as well.
