What occurs in pseudopregnancy?

• A. Fertilization does not occur but the female shows signs of being pregnant.
• B. Fertilization occurs but the pregnancy does not go further.
• C. Fertilization occurs outside the uterus in the abdominal cavity.
• D. The female is induced to ovulate

Answer: (A)

Pseudopregnancy occurs when a female goes through pregnancy-like hormonal and physical changes after ovulation but without fertilization. After ovulation the corpus luteum forms and secretes progesterone, creating a hormonal environment that mimics early pregnancy. Because there is no embryo to implant, there is no actual pregnancy, even though signs such as mammary development or nesting behavior may be present. This is why the best description is that fertilization does not occur but the female shows signs of being pregnant. Other scenarios involve actual fertilization with no progression, ectopic fertilization, or mechanisms that induce ovulation, which aren’t what pseudopregnancy describes.
