Outcomes
Primary outcome [1] 287973 0
That Premenopausal females have fewer hormone deficiencies compared to males and postmenopausal females post-operatively for treatment of non functioning pituitary macroadenomas. This will be assessed by the collection of biochemical hormone blood test. The hormonal assessment is routine part of clinical management of this condition. We aim to collect this data.

6 months post surgery
Secondary outcome [1] 299164 0
That Intrasellar pressure measured at the time of operation is lower in premenopausal females compared to males and postmenopausal females. This measurement of intrasellar pressure will be measured at the time of surgery using a commercial kit - Codman Intracranial Pressure Monitoring Kit (Camino Laboratories San Diego CA). At surgery, dura is exposed by removal of the bony sella floor, and a 1.5mm dural opening made allowing insertion of the fiberoptic transducer tip into the pituitary tumour with minimal chance of tumour extravasation. When a stable waveform is present on the pressure monitor, mean ISP is recorded and the catheter removed, with surgery proceeding as usual. This procedure will take 3-5 minutes.
Timepoint [1] 299164 0
Measured at the time of surgery
Secondary outcome [2] 299190 0
The measurement of Quality of life of participants pre and 6 month post surgery: that quality of life remains unchanged. This will be undertaken by a a validated questionnaire SF36- 4 week recall. Participants will undertake the questionnaire pre-operatively and 6 months post-peratively, with each participant acting as their own control
Timepoint [2] 299190 0
Pre-operatively and 6 months post-operatively
