    So, the correct option is 'Embedding of embryo in the thick lining of uterus'.
  • Question 2
    1 / -0
    The tube-like structure in the human male reproductive system, which carries sperm from epididymis to towards urethra is called:
    Solution

    A.Ureter - The duct by which urine passes from the kidney to the bladder or cloaca. It is tube like, carries spermis from epididymis towards urethera.

    B.Vas deference – They are a pair of uncoiled straight tubes, each arising from cauda epididymis.

    C.Seminal vesicles – They are a pair of contorted, musculoglandular sacs, which coccur between urinary bladder and rectum.

    D.Prostrate gland – It is a large, greyish-brownish pyramidal gland of the size of golf ball.
    So,t he correct option is 'Ureter'.
  • Question 3
    1 / -0
    The main function of mammalian corpus luteum is to produce
    Solution
    Corpus leuteum is yellow body produced after the release of egg/ovum
    Corpus leuteum produces progesterone, estradiol, inhibin A and small amount of estrogen. It is responsible for maintaining the endometrium during pregnancy.
    So, the correct answer is 'Progesterone'
  • Question 4
    1 / -0
    Sertoli cells are found in
    Solution
    Sertoli cells are present in convulated seminiferous tubules in testes where production of spermatozoa take place. Satellite cells provide nutrition to developing germ cells.
    So, the correct option is 'Seminiferous tubules and provide nutrition to germ cells'.
  • Question 5
    1 / -0
    The time for optimum chances of conception in a woman is starting from the day of menstruation.
    Solution
    This is usually about 14 days after the first day of your last period if your cycle is around 28 days long. An egg lives for about 12-24 hours after being released. For pregnancy to happen, the egg must be fertilized by sperm within this time. Sperm can live for up to 7 days inside a woman's body.

    So, the correct option is 'Option C, 14th day'.
  • Question 6
    1 / -0
    Male accessory glands include.
    Solution
    The seminal vesicles, the prostate, and the bulbourethral glands all contribute to the production of semen. Seminal vesicles release up to 60% of the fluid found in semen. The other 40% is produced by the prostate and bulbourethral glands. 
    so, 'the correct option is 'All of these'
  • Question 7
    1 / -0
    Which covering of testis is indicative of its abdominal original?
    Solution
    The tunica vaginalis is the pouch of serous membrane that covers the testes. It is derived from the vaginal process of the peritoneum, which is the fetus precedes the descent of the testes from the abdomen into the scrotum. So the correct option is 'Tunica vaginalis'.
  • Question 8
    1 / -0
    Which of the following is a set of male accessory ducts?
    Solution
    The male accessory ducts are rete testis, vasa efferentia, epididymis, and vas deferens. The function of rete testis is to store sperms produced by seminiferous tubules; while vasa efferentia helps to transport sperms from rete testis to epididymis. Epididymis provides nutrition for the maturation of sperms and vas deferens conduct the transport of sperms from the epididymis to urethra. 
    So, the correct answer is option B, Rete testis, vasa efferentia, epididymis and vas deferens. 
  • Question 9
    1 / -0
    Identify the A, B, C and D in given diagram of male reproductive system and choose correct option.

    Solution
    1. A is labelled Ejaculatory duct and it does not form a part of urinary system. Hence, it only recieves semen and no urine.
    2. B represents the unpaired prostate gland. The prostate gland secretes a fluid that nourishes and protects sperm.
    3. C represents urethra which carries urine and Siemens and runs through corpora spongiosum.
    4. Vas deferens does not contain the secretions of accessory glands but only sperms.
    So, the correct option is 'B- Prostate : Unpaired accessory sex gland in male'.
  • Question 10
    1 / -0
