Questions Related to male reproductive system in humans
Testes of man occur
-
Inside body
-
Upper side of body
-
On either side of dorsal aorta
-
In scrotal sacs
- Testes are the glandular glands that secrete hormone as well as produces male gametes.
- It is located in the scrotal sac, outside the body, because the process of spermatogenesis (sperm or male gamete production) requires a lower temperature i.e., 2-3${^0}$C lower than the normal body temperature.
The ................ is primary reproductive organ in male.
-
Testis
-
Ovary
-
Breast
-
Scrotum
The testes are a pair of ovoid glandular organs that are primary to the function of the male reproductive system. Its function is to produce sperm cells and the male sex hormone, testosterone.
So, the correct answer is option A.
If the migration of testes does not take place in man, from abdominal cavity to scrotal sac, then
-
Man will die.
-
The development of male secondary sex character will not take place.
-
The development of male reproductive system will not take place.
-
The formation of sperms will not take place.
In mammals, the process of spermatogenesis or the formation of sperm requires a lower temperature than the normal body temperature to produce viable sperms. Hence, the sperms are stored outside the body in a sac-like structure called scrotum.
So, if the testes do not move from abdominal cavity to the scrotal sac, the sperms will not be formed.
Thus, the correct answer is option D.
Testes produce male sex hormone
-
Estrogen
-
Testosterone
-
Follicle stimulating hormone
-
All of the above
How many sperms take part in fusion with female gamete?
-
Only one
-
Two
-
Millions in number
-
None of the above
The semen, secreted by male contains 100-200 millions of sperms. The healthy sperms in the semen then go to the cervix, then pass through the uterus and then ultimately arrive at the ampulla part of the fallopian tube where they come to meet the ovum. Although so many sperms encircle the ovum, only one sperm is allowed to penetrate the ovum.
Thus, the correct answer is option A.
Sperms in male are produced in
-
Testes
-
Urethra
-
Epididymis
-
Penis
The testes are the male gonads in animals. The primary function of the testes is to produce sperms and to produce the testosterone hormone.
So, the correct answer is option A.
In mammals, the testes lie in the scrotal sacs due to the
-
Presence of urinary bladder
-
Presence of rectum
-
Long vas-deferens
-
Requirement of low temperature for sperm formation
The process of spermatogenesis or the formation of sperms require a lower temperature (1-6 degree C lower) than the normal body temperature to produce viable sperms. Hence, the sperms are stored outside in a sac-like structure called scrotum.
So, the correct answer is option D.
Testes produce
-
Ovum
-
Estrogen
-
Sperm
-
All of the above
- The testes are the male gonad in the animals, produces sperm and the testosterone hormone and so is the primary male reproductive organ.
- Ovum is produced by the female reproductive organ, ovary, which is also responsible for the production of estrogen.
Each ejaculate of a man contains about how many sperm?
-
200
-
2000
-
200,000
-
200,000,000
Which one is primary sex organ?
-
Penis
-
Scrotum
-
Testis
-
Prostrate
- The reproductive organs in each gender include a primary sex organ and several secondary sex organs.
- The primary sex organ is the one that produces the gametes of that sex i.e. the sperm or the ova.
- So, in the male, the primary sex organ is testis. In the female, the primary sex organ is the ovary.
