New Delhi, June 19: Increase of prolactin hormone is the reason of women lactating without pregnancy, is a sign of infertility, say doctors.
It is due to hyperprolactinemia in which woman also witness loss of menstrual cycles and libido.
Proclactin’s work is to increase breast development during pregnancy and starts lactation. More than 75 per cent of the women in this condition produce milk without being pregnant.
“In hyperprolactinemia, there is a rise of prolactin hormone over the normal level. High levels interfere with estrogen production and cause changes in ovulatory cycles leading to irregular menstrual periods. Though not very common, high levels of prolactin in men can lead to loss of impotency, erectile and dysfunction,” said Arvind Vaid, IVF specialist.
“This decrease in level of gonadotropin-releasing hormone in turn decrease the secretion of luteinizing hormone and follicle stimulating hormone leading to infertility,” said Vaid.
“In some cases, changes in menstrual flow is marked along with amenorrhoea. Even on not being pregnant, breast produces milk with pain due to tissue changes there with increased levels of prolactin and loss of libido also causing vaginal dryness,” said Simanti Pathak, gynaecologist at Safdarjung hospital.
“In case if the prolactin levels are very high, a tumor may be suspected and in that case, MRI of the brain and pituitary glands is advised that uses high frequency radio waves to obtain images of the tissues and the size of tumor,” said IVF expert Parth Joshi.
