FSH:
1. Acts on Sertoli cells and stimulates secretion of some factors that help in spermiogenesis
2. Acts on Sertoli cells and inhibits secretion of some factors that help in spermiogenesis
3. Acts on Leydig cells and stimulates secretion of some factors that help in spermiogenesis
4. Acts on Leydig cells and inhibits secretion of some factors that help in spermiogenesis

(4) Secondary oocytes that have been arrested at the Metaphase II of Meiosis II
What is released at ovulation?
(1) Primary oocyte arrested at meiosis I
(2) Primary oocyte arrested at meiosis II
(3) Secondary oocyte arrested at meiosis I

II. Fertilization can occur if the ovum and the sperms are simultaneously transported to the fallopian tubes.
1. Both I and II are correct and II correctly explains I
2. Both I and II are correct but II does not explain I
3. I is correct but II is incorrect
4. I is incorrect but II is correct
