Such contracts should specify that the recipients are the legal parents of the child and the legal owners of any eggs or embryos resulting from the cycle; in other words, while the donor has the right to cancel the cycle at any time prior to egg donation (although if she does so the contract generally provides that she will not be paid), once the eggs are retrieved they belong to the recipient(s). In individual cases the donors and parents may also wish to negotiate terms relating to any unused embryos (e.g., some donors would prefer that unused embryos be destroyed or donated to science, while others would prefer or allow them to be donated to another infertile couple). Some states have also adopted the Uniform Parentage Act, which provides that the recipient or recipients have complete parental responsibility of the conceived child. In Buzzanca v. Buzzanca, 72 Cal. Rptr.2d 280 (Cal. Ct. App. 1998), the court held that both the recipient and the father of a child conceived through anonymous sperm and egg donation and carried by a surrogate were the legal parents of the child by virtue of their procreative intent. Therefore, the father was required to pay child support even though he sought a divorce before the child was born. Donor registries
A donor registry is a registry to facilitate donor conceived people, sperm donors and egg donors to establish contact with genetic kindred. They are mostly used by donor conceived people to find genetic half-siblings from the same egg- or sperm donor.
Many patients report influenza-like symptoms hours after taking interferon beta that usually improve within 24 hours, being such symptoms related to the temporary increase of cytokines. This reaction tends to disappear after 3 months of treatment and its symptoms can be treated with over-the-counter nonsteroidal anti-inflammatory drugs, such as ibuprofen, that reduce fever and pain. Another common transient secondary effect with interferon-beta is a functional deterioration of already existing symptoms of the disease. Such deterioration is similar to the one produced in MS patients due to heat, fever or stress (Uhthoffs phenomenon), usually appears within 24 hours of treatment, is more common in the initial months of treatment, and may last several days. A symptom specially sensitive to worsening is spasticity. Interferon-beta can also reduce numbers of white blood cells (leukopenia), lymphocytes (lymphopenia) and neutrophils (neutropenia), as well as affect liver function. In most cases these effects are non-dangerous and reversible after cessation or reduction of treatment. Nevertheless, recommendation is that all patients should be monitored through laboratory blood analyses, including liver function tests, to ensure safe use of interferons.The injection-site reactions can be mitigated by rotating injection sites or by using one of the medications that requires less frequent injections. Side effects are often onerous enough that many patients ultimately discontinue taking Interferons (or glatiramer acetate, a comparable disease-modifying therapies requiring regular injections).

Clinically isolated syndrome
The earliest clinical presentation of relapsing-remitting multiple sclerosis is the clinically isolated syndrome (CIS), that is, a single attack of a single symptom.
