	a.	the corpus albicans only makes estrogens
	b.	the interstitial cells of Leydig make testosterone
	c.	the LH surge in females triggers ovulation
	d.	FSH in males causes the interstitial cells of Leydig to produce testosterone
	e.	the LH surge in females causes the primary oocyte, that was arrested in prophase I, to complete meiosis I and to become a secondary oocyte arrested in metaphase II
	f.	LH in males causes spermatogenesis and spermeogenesis
	g.	the LH surge in females causes the primary oocyte to complete meiosis and become a mature ovum
	h.	both males and females make FSH and LH

Answer 1

I shall explain each point hereby.

a. Corpus Albicans as such does not make estrogen and is a remnant of corpus luteum which produces estrogen and progesterone. Therefore this can be deselected.

b. The statement is true and shall be selected.

c. The statement is true and shall be selected.

d. It is LH in males that causes interstitial cells of Leydig cells to produce testosterone. Therefore this point can be deselected.

e. Here, the secondary oocyte is arrested in metaphase 1 and not metaphase 2. Therefore this option can be deselected.

f. LH is associated with only spermatogenesis. It is FSH that helps in spermatogenesis and hence the option shall be deselected.

g. This statement is true and shall be selected.

i. This statement is true and shall be selected.
