Changes in GnRH pulse frequency in females is controlled by circulating levels of :

1.	estrogen and inhibin	2.	progesterone only
3.	progesterone and inhibin	4.	estrogen and progesterone

Which of the following pairs of hormones are not antagonistic (having opposite effects) to each other?
1. Insulin Glucagon
2. Aldosterone Atrial Natriuretic Factor
3. Relaxin Inhibin
4. Parathormone Calcitonin

Sertoli cells are regulated by the pituitary hormone known as:
1. FSH
2. GH
3. Prolactin
4. LH

The testes in the initial months of the development:
1. are found in the abdominal cavity.
2. descend into the scrotum by the end of second month.
3. start spermatogenesis.
4. secretes some LH.

Spermatogenesis takes place in:
1. interstitial space.
2. seminiferous tubules.
3. epididymis.
4. rete testis.

The sperms get stored and matured in:
1. seminal vesicles
2. seminiferous tubules
3. vas deferens
4. epididymis

Chose the correct chronological order of the male duct system beginning from the seminiferous tubules:

GnRH release by hypothalamus would be decreased due to:
1. decreased inhibin
2. increased testosterone
3. decreased FSH
4. decreased LH

During oogenesis, the first polar body:
1. is formed before fertilization.
2. is formed after fertilization.
3. develops into the ootid.
4. does not have chromosomes.

In fallopian tube, the part called as the ampulla:
1. opens into the uterus.
2. is the narrowest part.
3. is connected to the isthmus of the fallopian tube.
4. is lined with stratified squamous epithelium.
