Solution
The correct option is C The urge for sex is highly suppressed during the oestrous phase.
The female individuals of most of the animal species in their reproductive phase undergo physical and physiological changes which are regulated by hormonal changes in their body. Once the animal enters into its reproductive phase, its body undergoes certain changes physically as well as physiologically which are regulated by hormones. These changes can be recurring in nature, hence can also be referred to as cycles, or more precisely- reproductive cycles (since these cycles occur in the reproductive phase).
The reproductive cycle in non-primate mammals is called an oestrous cycle, which can be polyoestrous (more than one cycle) or monoestrous (one cycle). When many cycles occur throughout the year, it is called a non-seasonal polyestrous cycle. It continues throughout the year without a gap. E.g:- cows, pigs, rats, etc. In such animals, the urge for sex is very high during this period.
The menstrual cycle is similar to the non-seasonal polyestrous cycle, but here the cycles are present all throughout the year. The animals are sexually reproductive throughout their cycle, irrespective of fertility. Here, during menstruation, sloughing off of inner lining of the uterus or womb occurs accompanied by blood flow and passing out of the broken endometrium. It occurs mostly in primates- humans, chimpanzees, monkeys etc.
