Lack of menstruation may be indicative of pregnancy. During pregnancy, the levels of estrogen and progesterone are high in the blood, which are required for the maintenance of uterus and thus, menstruation does not occur. On 14th day of the menstrual cycle, there is rapid increase in LH (called LH surge), that induces ovulation. The changes in the ovary and the uterus are induced by changes in the levels of ovarian hormones and pituitary hormones. If fertilisation occurs, corpus luteum degenerates by 16th week of pregnancy.

Menstrual Cycle
The menstrual cycle is a monthly series of changes that occur in a woman's body in preparation for pregnancy. It involves the release of an egg from the ovary, the thickening of the uterine lining, and the shedding of this lining if fertilization does not occur. Let's analyze the given statements to determine which ones are correct.
Lack of menstruation may be indicative of pregnancy.
This statement is correct. When a woman becomes pregnant, the fertilized egg implants itself into the uterine lining, preventing its shedding. As a result, menstruation does not occur. Therefore, a missed period can be an early sign of pregnancy.
The changes in the ovary and the uterus are induced by changes in the levels of ovarian hormones only.
This statement is incorrect. While ovarian hormones, such as estrogen and progesterone, play a crucial role in regulating the menstrual cycle, other hormones also contribute to the changes in the ovary and uterus. The pituitary gland releases follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which stimulate the growth and maturation of ovarian follicles and the release of an egg (ovulation), respectively.
LH surge induces ovulation.
This statement is correct. Prior to ovulation, there is a surge in LH levels, which triggers the release of a mature egg from the ovary. This surge occurs around the middle of the menstrual cycle.
If fertilization occurs, corpus luteum degenerates immediately.
This statement is incorrect. After ovulation, the ruptured ovarian follicle transforms into a structure called the corpus luteum, which secretes progesterone. If fertilization occurs, the developing embryo releases a hormone called human chorionic gonadotropin (hCG), which maintains the corpus luteum. The corpus luteum continues to produce progesterone, which is essential for maintaining the uterine lining and supporting pregnancy. If fertilization does not occur, the corpus luteum degenerates, leading to a decrease in progesterone levels and the shedding of the uterine lining.
In summary, the correct statements about the menstrual cycle are:
(i) Lack of menstruation may be indicative of pregnancy.
(iii) LH surge induces ovulation.
