Final answer:
Hyperprolactinemia causes symptoms in females, while Polycystic Ovary Syndrome (PCOS) causes symptoms in males.
Step-by-step explanation:
The condition that causes symptoms of loss of period (amenorrhea), reduced libido, breast milk secretion, and infertility in females is Hyperprolactinemia. Hyperprolactinemia occurs when there is an overproduction of prolactin, a hormone that stimulates breast milk production. It can be caused by conditions such as pituitary tumors or certain medications.
On the other hand, the symptoms of progressive loss of libido, impotency (erectile dysfunction), low sperm counts, and breast enlargement in males are associated with Polycystic Ovary Syndrome (PCOS). PCOS is a hormonal disorder characterized by the presence of multiple cysts in the ovaries. It can lead to imbalances in sex hormone levels, causing the symptoms mentioned.
