Yes, prolactin inhibits ovulation. Elevated levels of prolactin can disrupt the normal hormonal balance necessary for ovulation by suppressing the secretion of gonadotropin-releasing hormone (GnRH). This, in turn, leads to reduced levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are essential for the ovarian cycle and ovulation. Therefore, high prolactin levels can result in irregular menstrual cycles or amenorrhea.

What are the functions of prolactine?
In females, prolactin tell the breasts to start producing milk (but it is another hormone, oxytocin, that actually causes the milk to be excreted). In both sexes, prolactin also inhibits LH and FSH release, which inhibit estrogen/progesterone secretion and ovulation in females, and testosterone secretion and sperm production in males. Overproduction of prolactin (like from a tumor or a dopamine antagonist) can cause infertility and decreased sex drive in both sexes.
