What statement indicates a woman has correct information about oogenesis?

"Women have all of their ova at the time they are born."

"Women make fewer ova as they age."

"Ova production begins at birth and continues until puberty."

"New ova are made every month from puberty to climacteric."

Answer and Explanation

The Correct Answer is A

A. Women have all of their ova at birth. Oogenesis, the process of egg development, occurs in the fetus, and women are born with all the eggs (ova) they will ever have. The number of eggs decreases over time.

B. Women make fewer ova as they age is correct in a sense, but the statement is misleading because the number of eggs actually decreases after birth, not through an ongoing process of "making fewer."

C. Ova production begins at birth and continues until puberty is incorrect. Ova are formed during fetal development, but no new eggs are produced after birth.

D. New ova are made every month from puberty to climacteric is incorrect. While ova mature and are released monthly during a woman's reproductive years, they are not newly made each month. The ovary contains a finite number of immature eggs at birth.

Correct Answer is B

Explanation

A. Implantation of the zygote does not affect the determination of biological sex. The biological sex is already determined at the time of fertilization.

B. Sex chromosomes (XX for female and XY for male) determine biological sex. This combination is established at fertilization when the sperm and egg combine to form the zygote.

C. The foramen ovale is a hole in the fetal heart that allows blood to bypass the lungs in utero and is unrelated to the determination of biological sex.

D. The blastocyst formation is an early developmental stage after fertilization but does not determine biological sex. It is the combination of sex chromosomes that determines whether the fetus is male or female.

A. Drinking extra milk during pregnancy allows breasts to produce adequate amounts of milk. B. Supplementing breastfeeding with formula allows the infant to receive adequate nutrition. C. Breast size can be increased with exercise. D. Milk is produced in ducts and lobules regardless of breast size.

Correct Answer is D

Explanation

A. Drinking extra milk during pregnancy does not directly impact milk production. The body produces milk based on demand, not by consuming additional milk.

B. While formula supplementation may be necessary in some cases, it does not directly address the mother's ability to produce sufficient milk. It is important to focus on breastfeeding techniques and frequency to support milk production.

C. Breast size is not a determining factor for successful breastfeeding. Exercises will not increase breast size or enhance milk production significantly.

D. Milk production occurs in the mammary glands, specifically in the ducts and lobules, which are not dependent on breast size. Even women with smaller breasts can produce enough milk to exclusively breastfeed, as long as the demand and milk removal are properly managed.
