Answer
a) An abnormal condition results when testes of a male boy do not descend into scrotum during his embryonic development and it leads to sterility i.e., incapability to produce sperms as sperm formation 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 if it is plugged. This is known as vasectomy and is a surgical birth control method for males.
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) If placenta does not attach to the uterus optimally, nutrition and oxygen will not be provided to the growing embryo affecting its growth, which could have serious implications on development of the embryo.
