Which of the following statements about cervical mucus during the menstrual cycle is correct?

It is thick and acidic throughout the cycle, preventing sperm passage.
It becomes thin and alkaline around ovulation, facilitating sperm passage.
It remains unchanged in consistency during the cycle.
It is only produced after fertilization occurs.
2

During the peri-ovulatory phase, cervical mucus becomes thin and alkaline to help sperm move easily towards the ovum.

Which phase of the menstrual cycle is marked by the regrowth of the endometrium after menstruation?

Menstrual phase
Proliferative (follicular) phase
Ovulatory phase
Luteal phase
2

The proliferative phase, part of the follicular phase, is when estrogen promotes the regrowth of the endometrium following menstruation.

Which event marks the completion of oocyte maturation in humans?

Meiosis I with formation of polar bodies
Formation of the secondary oocyte arrested at metaphase II
Completion of meiosis II
Ovulation of the primary oocyte
2

Oocyte maturation is marked by the formation of a secondary oocyte that arrests at metaphase II until fertilization occurs.

Which hormone, produced by the ovaries, inhibits FSH secretion to regulate follicular development?

Estrogen
Progesterone
Inhibin
Oxytocin
3

Inhibin, produced by granulosa cells of the ovary, specifically inhibits FSH secretion to prevent overstimulation of follicular development.

Which segment of the fallopian tube is the most common site for fertilization?

Infundibulum
Ampulla
Isthmus
Interstitial part
2

The ampulla is the widest segment of the fallopian tube and is the most common site for fertilization.

Which of the following is NOT a primary function of seminal fluid?

Nourishes and transports sperm
Provides an alkaline medium to neutralize vaginal acidity
Stimulates sperm motility
Directly secretes testosterone
4

Testosterone is produced by the testes (Leydig cells), not by the accessory glands that contribute to seminal fluid.

Which of the following is responsible for maintaining the corpus luteum during early pregnancy?

Luteinizing hormone (LH)
Follicle-stimulating hormone (FSH)
Human chorionic gonadotropin (hCG)
Progesterone
3

hCG, secreted by the trophoblast, maintains the corpus luteum and ensures continued progesterone production during early pregnancy.

Where does fertilization typically occur in the human female reproductive tract?

Uterus
Cervix
Fallopian tube
Ovary
3

Fertilization usually takes place in the fallopian tube, where the sperm meets the ovum.

Which of the following assisted reproductive techniques involves the direct transfer of a fertilized egg into the fallopian tube?

In vitro fertilization (IVF)
Zygote intrafallopian transfer (ZIFT)
Gamete intrafallopian transfer (GIFT)
Intrauterine insemination (IUI)
2

ZIFT involves fertilization in vitro and the transfer of the resulting zygote into the fallopian tube.

Which of the following disorders is characterized by multiple ovarian cysts, irregular menstrual cycles, and hyperandrogenism?

Endometriosis
Polycystic Ovary Syndrome (PCOS)
Uterine fibroids
Primary amenorrhea
2

PCOS is marked by the presence of multiple cysts on the ovaries, irregular cycles, and elevated androgen levels.
