Answer 1

The correct option is C 3

During pregnancy, the menstrual cycle is suspended due to an increase in progesterone and low level of oestrogen.

Human males ejaculate about 200 to 300 million sperm during coitus because one ml of semen contains about a hundred million sperm. During the coitus the male releases around two to three ml of semen.

Each testis of the human male has about 250 compartments which are known as testicular lobules that contain sperms and are known as seminiferous tubules.

Sperm formation in men continue throughout the life but ovum formation stops around 50 to 55 year of age in female and this period is known as.

menopause.

So, the correct option is '3'
