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."
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 C
Explanation
A. Procoagulant factors, not decreased procoagulant factors, increase during pregnancy, which contributes to a hypercoagulable state.
B. Natural anticoagulants, such as antithrombin, tend to decrease during pregnancy, which actually heightens the risk of clot formation rather than mitigating it.
C. Increased blood plasma volume and elevated levels of clotting factors during pregnancy contribute to a hypercoagulable state. This adaptation helps prevent excessive bleeding during childbirth but also increases the risk of thrombosis.
D. Platelet counts do not typically increase during pregnancy; in fact, they may slightly decrease due to hemodilution, though their function remains intact.
Correct Answer is A
Explanation
A. Sperm production is temperature-sensitive, and the testes require a slightly cooler environment than the rest of the body. Increased warmth, such as from tight clothing, prolonged sitting, or heat exposure, can impair spermatogenesis.
B. The size of the penis and testes is not directly correlated with sperm production. The functionality of the testes, not their size, determines sperm output.
C. Infrequent sexual intercourse can affect fertility by decreasing opportunities for conception but does not directly decrease sperm production.
D. Circumcision status does not affect sperm production, as it primarily pertains to hygiene and the prevention of certain infections.
