While such therapy buys time for patients, it is not a cure, as inevitably the cancer becomes resistant to the androgen deprivation and continues to grow.

Menstrual status and long-term cardiovascular effects of intense exercise in top elite athlete women’

It has long been assumed that menstrual disorders amongst elite female athletes are related to tough training regimes combined with insufficient energy intake.
