Elevation of prolactin level in normal female causes:
- ANon implantation
- BNon ovulation
- COligo ovulation
- DOvarian cysts
Explanation:
In humans, implantation is the stage of pregnancy at which the embryo adheres to the wall of the uterus.
High levels of prolactin can also be caused by pituitary tumors, certain medications.
Women with elevated prolactin levels who are trying to conceive(give birth) may experience menstrual and/or ovulatory cycles that are irregular, making it more difficult to become pregnant.
Thus higher levels of prolactin cause non-implantation by preventing fertilization by affecting ovarian cycles.
Hence Elevation of prolactin level in normal female causes non-implantation.
