| 1. | The scrotum can contain lengthy ducts for the transfer of sperms |
| 2. | Scrotum helps in maintaining the low temperature of the testes necessary for spermatogenesis |
| 3. | Scrotum reduces the pressure around testes necessary for spermatogenesis |
| 4. | Scrotum can store huge amounts of sperms |

(1) Peritoneum
(2) Adipose tissue
(3) Ligaments
(4) Areolar tissue
Consider the following two statements:
I. The hymen is often torn during the first coitus.
II. The presence or absence of hymen is reliable indicator of virginity.
Of the two statements:
1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is correct but II is incorrect

What causes the onset of puberty in males?
1. Increase in secretion of testosterone by testis
2. Decrease in secretion of testosterone by testis
3. Increase in secretion of GnRH by hypothalamus

For normal fertility, what percent of the sperm in ejaculate must exhibit normal morphology?
1. 20
2. 30
3. 40

At the birth of the female child, the follicles in her ovaries contain:
| 1. | Primary oocytes that have been arrested at the S phase of the cell cycle |
| 2. | Primary oocytes that have been arrested at the Prophase I of Meiosis I |
| 3. | Secondary oocytes that have been arrested at the Prophase I of Meiosis I |
| 4. | Secondary oocytes that have been arrested at the Metaphase II of Meiosis II |
The division of primary oocyte results in:
(1) unequal cells – a smaller haploid secondary oocyte and a larger diploid polar body
(2) unequal cells – a larger haploid secondary oocyte and a smaller haploid polar body
(3) unequal cells – a smaller diploid secondary oocyte and a larger haploid polar body
(4) equal cells – a haploid secondary oocyte and a haploid polar body
The correct sequence of the various phases of a typical menstrual cycle is:
(1) Menstrual → Follicular → Secretory → Ovulatory
(2) Menstrual → Follicular → Ovulatory → Secretory
(3) Ovulatory → Follicular → Secretory → Menstrual
(4) Menstrual → Secretory → Follicular → Ovulatory
Which hormone is mainly secreted by the developing follicles during the proliferative phase of the menstrual cycle?
| 1. | LH | 2. | FSH |
| 3. | Progesterone | 4. | Estrogen |
Corpus luteum secretes large amounts of:
| 1. | LH | 2. | FSH |
| 3. | Progesterone | 4. | Estrogen |
In the absence of fertilization, corpus luteum:
(1) Stops secreting progesterone but increases the secretion of estrogen
(2) Stops secreting estrogen but increases the secretion of progesterone
(3) Increases the secretion of both progesterone and estrogen
(4) Degenerates
What ensures that only one sperm can fertilize the ovum?
(1) Corona radiata
(2) Ground substance around ovum
(3) Zona pellucida
(4) Acrosome
In humans, the sex of the baby is determined:
1. At the time of fertilization and by the father
2. At the time of fertilization and by the mother
3. At the time of implantation and by the father
4. At the time of implantation and by the mother
Morula is a solid ball of cells during early embryonic development and consists of:
(1) 4 – 8 cells
(2) 8 – 16 cells
(3) 24 – 30 cells
(4) 60 – 72 cells
During pregnancy the levels of thyroxin:
(1) Increase several folds in maternal blood
(2) Increases several folds in fetal blood
(3) Decreases several folds in maternal blood
(4) Decreases several folds in fetal blood
The fetal body is covered with fine hair, eyelashes separate, and eyelashes are formed by the end of:
| 1. | 20 weeks | 2. | 24 weeks |
| 3. | 28 weeks | 4. | 30 weeks |
The signals of fetal ejection reflex originate from:
1. Maternal pituitary
2. Maternal hypothalamus
3. Fully developed fetus and placenta
4. Fetal pituitary
To induce uterine contractions for parturition which of the following hormones can be injected to the female?
(1) hCG
(2) Estrogen
(3) Progesterone
(4) Oxytocin
The milk produced during the initial few days of lactation, called colostrum, is essential for the new born as colostrums contains:
(1) Large amount of glucose
(2) Anti-infective antibodies
(3) Fats
(4) Various hormones
