Final answer:
Theca lutein cysts are primarily treated through observation, as they usually resolve once the underlying condition is treated. In vitro fertilization or surgical removal of an oviduct obstruction may be recommended to a couple trying to conceive.
Step-by-step explanation:
The proper treatment for theca lutein cysts involves observation, as they typically resolve on their own once the associated condition causing them, such as a hormonal imbalance or the presence of high levels of hCG (human chorionic gonadotropin), is addressed. Antibiotics are not effective as theca lutein cysts are not caused by a bacterial infection. Hormonal therapy is not a direct treatment for these cysts, but may be part of the treatment of the underlying cause. Aspiration may be considered in cases where the cysts cause discomfort, or if there is a risk of ovarian torsion or rupture. However, this is less common. Generally, the condition triggering the theca lutein cysts, such as gestational trophoblastic disease, needs to be the focus of treatment rather than the cysts themselves. A couple trying to conceive might be advised to consider in vitro fertilization (IVF) if an obstruction in the oviducts is diagnosed, or possible surgical removal of the obstruction followed by reconnection of the fallopian tubes.
