Two Decades After Legislation on Identifiable Donors in Sweden: Are Recipient Couples Ready to be Open About Using Gamete Donation?
Two decades after legislation on identifiable donors in Sweden: are recipient couples ready to be open about using gamete donation?
BACKGROUND: Two decades after the introduction of Swedish legislation that allows children born as a result of gamete donation access to identifying information about the donor, a nationwide multicentre study on the psychosocial consequences of this legislation for recipients and donors of gametes was initiated in 2005. The aim of the present study was to investigate recipient couples attitudes and behaviour regarding disclosure to offspring and others, attitudes towards genetic parenthood and perceptions of information regarding parenthood after donation. METHODS: The present study is part of the prospective longitudinal Swedish study on gamete donation, including all fertility clinics performing donation treatment in Sweden. A consecutive cohort of 152 heterosexual recipient couples of donated oocytes (72% response) and 127 heterosexual recipient couples of donated sperm (81% response) accepted participation in the study. In connection with the donation treatment, male and female participants individually completed two questionnaires with study-specific instruments concerning disclosure, genetic parenthood and informational aspects. RESULTS: About 90% of participants (in couples receiving anonymous donated gametes) supported disclosure and openness to the offspring concerning his/her genetic origin. Only 6% of all participants had not told other people about their donation treatment. Between 26 and 40% of participants wanted additional information/support about parenthood following donation treatment. CONCLUSIONS: Two decades after the Swedish legislation of identifiable gamete donors, recipient couples of anonymously donated sperm and oocytes are relatively open about their treatment and support disclosure to offspring. Recipient couples may benefit from more information and support regarding parenthood after gamete donation. Further studies are required to follow-up on the future parents actual disclosure behaviour directed to offspring.This is a pre-copy-editing, author-produced PDF of an article accepted for publication:S Isaksson, A Skoog Svanberg, Gunilla Sydsjö, A Thurin-Kjellberg, P-O Karlstrom, N-G Solensten and C Lampic, Two decades after legislation on identifiable donors in Sweden: are recipient couples ready to be open about using gamete donation?, 2011, HUMAN REPRODUCTION, (26), 4, 853-860.http://dx.doi.org/10.1093/humrep/deq365Copyright: Oxford University Presshttp://www.oxfordjournals.org
Personality characteristics in a Swedish national sample of identifiable oocyte donors Personality characteristics in a Swedish national sample of identifiable oocyte donors
With regard to personality, a significant difference was evident between the two groups; oocyte donors showed lower means for Harm Avoidance and higher scores for Persistence than the controls. This indicates that the donors felt less worried and displayed a lower level of fear of uncertainty, shyness and fatigability and a higher level of persistence than the controls. In the present sample, 29 (16%) of the donors were so called "known donors" i.e. the recipient couples and the donors were known to each other. "Known donors" displayed a mature and stable character. Conclusion: In this nationwide oocyte donor program we found that the women who had been accepted for inclusion in the donation program were all well adjusted and mature
Reducible Dehn-filling 3-manifolds and two-bridge knot-group representations
Given a knot 1C in the manifold S3, the operation of drilling out a tubular neighbourhood of the knot and then gluing in a solid torus such that its meridian curve goes to a (p, q)-curve on the torus boundary of the knot exterior is called Dehn surgery. In nontrivial cases, the product of this operation is a manifold different from S3. We examine this operation, first by fixing properties of the resulting manifold in order to deduce the surgery knot, then by fixing the knot to deduce properties of the resulting manifold.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
