Parhaan hoitovaihtoehdon valitsemiseksi kartoitamme ensin naisen ja miehen hedelmällisyyden tilanteen. Tämän perusteella laadimme yhdessä yksilöllisen hoitosuunnitelman. Terapeutin vastaanotolla käymme läpi lainsäädännöllisiä seikkoja ja elämäntilanteeseen liittyviä asioita. Pohdimme myös tulevaa elämää lapsen kanssa.
Keskustelua lainsäädännöstä ja elämäntilanteesta sekä yhdessä ja erikseen. Tässä vaiheessa tehdään päätös hoitoon lähtemisestä.
Hoitopolun ja hoitomuodon valinta. Hoitosuostumusten ja luovutussuostumusten tekeminen. Infektiotestien ajoitus valitun hoitopolun mukaisesti.
Siittiöt voidaan tarvittaessa pakastaa myöhempää käyttöä varten.
Hoito tapahtuu yleisimmin inseminaatiolla eli keinohedelmöityksellä. Tarvittaessa voidaan käyttää koeputkihedelmöityshoitoa, joka on inseminaatiota tehokkaampi hoitomuoto. Myös luovutettujen munasolujen, siittiöiden tai alkioiden käyttö on mahdollista.
The Maternity Act, the Act on Assisted Fertility Treatments, and the so-called Tissue Act, among others, regulate parenthood and fertility treatments. According to the Maternity Act, a child can have several guardians; however, the law stipulates that there can only be two legal parents. Before treatment, the clinic prepares the documents required by the Act on Assisted Fertility Treatments, a treatment consent and a possible donation consent, on the basis of which legal parenthood is determined. The treatment consent is made for the party receiving treatment, which can be an independent woman or a couple. A donation consent is made if the man wishes to act as a known donor confirming paternity in the treatment. Co-parenting parents can choose which treatment path they want to proceed with. The clinic's staff provides information and advice on different treatment options. We help you find the most suitable solution for your situation.
In this case, according to the law, you cannot be in a relationship elsewhere.
The consent for treatment is made together, thereby granting legal parenthood to both co-parents. The consent can be withdrawn at the wish of either party, which will end the treatments, and in this situation, any remaining embryos can no longer be used unless separate consent is given. The consent of both is always required for the use of embryos.
The man can be in a relationship elsewhere.
The woman gives consent for treatment. The man gives consent for donation, in the terms of which it is recorded that this is a dedicated donation to a specific recipient. In the consent for donation, the man states that he wishes to acknowledge paternity.
If he wishes, the man can cancel the consent for donation. In this case, the stored sperm is destroyed. In this situation, however, the single woman can continue to use the embryos created in the treatment for her own treatment, but paternity can no longer be confirmed. As a donor, the man has the right to decide on the use of his gametes, but he has no right of disposal over the use of the embryos created from them during the validity of the original consent for donation. Once the consent for donation has expired, the embryos can no longer be used.
If he wishes, the man can also cancel the confirmation of paternity while maintaining the validity of the consent for donation. In this case, the woman can still use the donor’s frozen sperm or embryos obtained in the treatment, but paternity will no longer be confirmed after the cancellation takes effect.
Cancellations and amendments of consent must always be made in writing at the clinic.
n fertility treatments, the treatment consent and donation consent determine legal parenthood. If the woman receiving treatment is in a relationship, her spouse is the future child's second legal parent. A man can act as a sperm donor, but cannot confirm his paternity.
You can get more information about co-parenting and related legal agreements from Sateenkaariperheet ry External link. Both international and Finnish studies have been conducted on the well-being of children in rainbow families, and according to them, children thrive just as well in rainbow families as in heterosexual families.
At Felicitas Mehiläinen, you receive multidisciplinary support at all stages of the treatment process from physicians, therapists, and nurses. The goal is always a balanced and successful family formation.
In co-parenting, the child's parents are not in a romantic relationship with each other, unlike in a traditional family. Parenthood is based on an agreement and a shared desire to raise a child together, even if the parents live separately.
A child can have several guardians, but according to the Parenthood Act, there can only be two legal parents. However, there can be multiple co-parenting parents who share the responsibility for the child's upbringing and daily life.
The legal parenthood is determined by documents in accordance with the Act on Assisted Fertility Treatments, such as the treatment consent and possible donation consent. These documents are prepared at the clinic before the treatment begins.
If the treatment consent is withdrawn by either party, the treatments will end. Any remaining embryos cannot be used without separate consent. The consent of both parties is always required for the use of embryos.
