Some form of potential or "capacity" is often seen as evidence of human moral status. Opinions differ as to whether the potential of the embryo should be regarded as such evidence. In this paper, I discuss some common arguments against regarding the embryo's potential as a sign of human status, together with some less common arguments in favour of regarding the embryo's potential in this way.

We have treated 34 patients with advanced prostate cancer, resistant to orchiectomy or oestrogen therapy, with aminoglutethimide. Seven patients (21%) showed improvement in pain and performance status for prolonged periods. By NPCP criteria six patients had stable disease and one had partial tumour response. Six of these patients remained on oestrogen therapy. Suppressed gonadotrophin levels (FSH and LH), despite orchiectomy, correlated strongly with benefit from aminoglutethimide. No relationships between response to treatment and changes in serum testosterone, dehydroepiandrosterone, oestradiol or prolactin were found. Six patients had side effects requiring cessation of therapy. A further 27 patients developed less severe toxicity. Despite its toxicity, these results show that aminoglutethimide has a role in the management of advanced prostatic cancer resistant to primary hormonal manipulation.
1. Data from long-term follow-up of subjects screened for hypertension indicate that the elevation of blood pressure represents a major contribution to community-attributable risk of death. 2. Attendance rates at screening, and drop-out rates from follow-up, have been assessed in studies in Glasgow. 3. Screening and follow-up are probably best conducted from general practice, and should be regarded as an extension of good primary care.
