Endocrine changes and symptomatology after oophorectomy in premenopausal women.

The symptomatic and endocrine changes following hysterectomy and bilateral oophorectomy have been studied in 100 patients, 1 to 31 years after surgery. The most frequent symptoms at the time of interview were depression (62 patients), insomnia (48 patients), loss of libido (46 patients) and dyspareunia (38 patients). Vasomotor symptoms were recorded in 28 patients. Although 94 patients claimed that hot flushes were the first symptomatic changes noticed, 60 had complete relief from these symptoms within 6 months of surgery; 34 patients had no symptoms and only 4 patients were taking oestrogen therapy at the time of interview. Plasma oestradiol and testosterone levels were 78 per cent and 27 per cent respectively below the mean values of day 1 to 10 of the menstrual cycle, similar to those found at comparable years after a normal menopause. The plasma FSH level was about 14 times and the plasma LH level about twice the respective preoperative value. Unlike after the normal menopause, these gonadotrophin levels did not show any decline with increasing age. There was no correlation between plasma hormone levels and the presence of vasomotor symptoms or depression.
