The ovary of teleosts is also often hollow, but in this case, the eggs are shed into the cavity, which opens into the oviduct . [30] Certain nematodes of the genus Philometra are parasitic in the ovary of marine fishes and can be spectacular, with females as long as 40 cm, coiled in the ovary of a fish half this length. [32] Although most normal female vertebrates have two ovaries, this is not the case in all species. In most birds and in platypuses , the right ovary never matures, so that only the left is functional. (Exceptions include the kiwi and some, but not all raptors , in which both ovaries persist. [33] [34] ) In some elasmobranchs, only the right ovary develops fully. In the primitive jawless fish , and some teleosts, there is only one ovary, formed by the fusion of the paired organs in the embryo. [30]

Many hormones and their structural and functional analogs are used as medication . The most commonly prescribed hormones are estrogens and progestogens (as methods of hormonal contraception and as HRT ), [13] thyroxine (as levothyroxine , for hypothyroidism ) and steroids (for autoimmune diseases and several respiratory disorders ). Insulin is used by many diabetics . Local preparations for use in otolaryngology often contain pharmacologic equivalents of adrenaline , while steroid and vitamin D creams are used extensively in dermatological practice.
