A pregnant woman asks the nurse, "Will I be able to have a vaginal delivery?" The nurse knows that which type of female pelvis is optimal for passage of the fetal head?

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.

A. Decrease in production of sebaceous gland secretions is incorrect. Testosterone actually increases sebaceous gland activity, leading to an increase in oil production, which can contribute to acne during puberty.

B. Increase in muscle mass and strength is correct. Testosterone plays a key role in the development of secondary male characteristics, including increased muscle mass, strength, and the growth of larger bones.

C. Stimulation of production of white cells and platelets is incorrect. While testosterone affects many bodily functions, it does not directly stimulate the production of white cells or platelets.

D. Promotion of growth of small bones is incorrect. Testosterone is more closely associated with the growth and development of larger bones (e.g., long bones), leading to height increases during puberty. It does not promote the growth of small bones.
