The shared terminal duct of the reproductive and urinary system in the human male is 

1. Urethra

2. Ureter

3. Vas deferens

4. Vasa efferentia

The main function of mammalian corpus luteum is to produce

1. estrogen only

2. progesterone

3. human chorionic gonadotropin

4. relaxin only

Select the correct option describing gonadotropin activity in a normal pregnant female

1. High level of FSH and LH stimulates the thickening of endometrium

2. High level of FSH and LH facilitate implantation of the embryo

3. High level of HCG stimulates the synthesis of estrogen and progesterone

4. High level of HCG stimulates the thickening of endometrium

Which one of the following is not the function of placenta?

1. facilitates supply of oxygen and nutrients to embryo

2. secretes oestrogen

3. facilitates removal of carbon dioxide and waste material from embryo

4. secretes oxytocin during parturition

Which one of the following statements is false in respect of viability of mammalian

sperm?

1. Sperm is viable for only up to 24 h

2. Survival of sperm depends on the pH of the medium and is more active in alkaline

medium

3. Viability of sperm is determined by its motility

4. Sperms must be concentrated in a thick suspension

In a normal pregnant woman, the amount of total gonadotropin activity was assessed.

The result expected was

1. High level of circulating FSH and LH in the uterus to stimulate implantation of the

embryo

2. High level of circulating HCG to stimulate endometrial thickening

3. High levels of FSH and LH in uterus to stimulate endometrial thickening

4. High level of circulating HCG to stimulate oestrogen and progesterone synthesis

The Leydig cells as found in the human body are the secretory source of

1. progesterone

2. intestinal mucus

3. glucagon

4. androgens

If for some reason, the vasa efferentia in the human reproductive system get blocked,

the gametes will not be transported from

1. epididymis to vas deferens

2. ovary to uterus

3. vagina to uterus

4. testes to epididymis
