Question

Number of sperms present in a single ejaculation of semen contains
A. 10,000
B. 1,00,000 – 10,00,000
C. 30 – 40 million
D. 300 – 400 million

Answer 1

Ejaculation is the final stage of male sexual stimulation and the natural goal, and an integral natural part of conception. This high production of sperm has evolved in order to increase fertilization chances.

Complete answer:
Human reproduction activities include the production of gametes i.e. sperm in males and ovum in females, the delivery of sperm to the female genital tract (insemination) and the combination of male and female gametes (fertilisation) leading to the development of zygotes.The male reproductive system is found in the pelvic area. It contains a set of testes along with glands, accessory ducts, and the external genitalia. Rete testis, vasa efferentia, epididymis, and vas deferens comprise the male sex accessory ducts. The seminiferous tubules of the testes open by rete testis into the vasa efferentia. The vasa efferentia exits the testis and opens in the posterior surface of each testis into epididymis. The epididymis leads to vas deferens which ascends into the abdomen and loops over the urinary bladder. It collects the seminal vesicle duct and opens as an ejaculatory duct into urethra.These ducts save and hold sperms through a urethra from the testis to the outside. The urethra comes from the urinary bladder and enters its outside opener called the urethral meatus through the penis.

Ejaculation is a male reproductive discharge of semen. A single ejaculation comprises between 300 million and 400 million sperm. Those that fertilise an ovum are a single sperm. This high production of sperm has evolved in order to increase fertilization chances.

Thus, the correct answer is option D. i.e., 300 – 400 million.
