| − | Sex hormones are produced by the zona reticularis of the adrenal glands in addition to those produced by the ovary and testis:
| |
| − | *'''Testis''': Produces '''androgens''':
| |
| − | **Increase mitoses in skin.
| |
| − | **Increase sebaceous secrretion.
| |
| − | **Increase hair growth.
| |
| − | *'''Ovary''': Produces '''oestrogens''' and '''progesterone'''. Effects of oestrogens include:
| |
| − | **Decreased collagen production.
| |
| − | **Decreased sebaceous secretion.
| |
| − | **Decreased epidermal thickness.
| |
| − | **Decreased hair growth.
| |
| − | **Increased skin pigmentation.

| − | '''''Ovarian Imbalance Type 1'''''
| |
| − | Seen in adult bitches who present with alopecia and increased pigmentation round the perianal, perigenital and axillary areas.
| |
| − | Caused by:
| |
| − | *Cystic ovaries.
| |
| − | *Ovarian neoplasia.
| |
| − | ===Males===
| |
| − | Dogs present with bilaterally symmetric alopecia, similar hyperpigmentation to that seen with female dogs with ovarian imbalance, loss of libido and gynaecomastia. The dogs become attractive to other male dogs.
