Through such direct actions as poor nutrition and second-hand smoke, maternal environment during gestation can directly influence everything from foetal birth weight to risk of future adult coronary disease. From that second or third degree cousin, traditional genealogy tools can be employed to rebuild a family tree up to the shared ancestor, such as vital records, death notices and obituaries, census records, or newspaper archives.

Third-party Reproduction: Sperm, Egg, and Embryo Donation and Surrogacy
Prospective donors must have a physical examination with screening for visible physical abnormalities, as well as testing for sexually transmitted diseases. On the day of transfer, between day 2 and day 5 after fertilization, as the case may be, the pre-embryos with the best developmental characteristics are selected. The woman is positioned on the examination table as if in preparation for a pelvic examination. A number of studies have shown that pregnancy rates using donor sperm with IUI are higher than with ICI when frozen semen is used. Embryo transfer donor egg fertilized by donor sperm is another option if the male is also infertile. In , of the 9, cycles resulting in an embryo transfer, 4, resulted in a live birth.
The Impact of Sperm and Egg Donation on the Risk of Pregnancy Complications.
The first regards the messages that such preferences send about and towards persons living with disabilities, ones which may be seen as discriminatory and offensive: One way of containing this risk would be to limit donor offspring numbers; another would be to allow donor anonymity, although that may be objectionable on other grounds see our earlier discussions of donor anonymity and donor offspring limits. One reason for prohibiting anonymous gamete donation is the distress that advocates of disclosure claim many donor-conceived children suffer as a consequence of the absence of identifying information about their biological progenitors. Increasing numbers of people are using the technology to uncover the identities of their donors. In addition to obligations that focus on the health of potential offspring and the competence of intending parents, another question is whether there ought to be limits on the number of offspring that can be created from a single gamete provider. Since bringing children into existence is a foreseeable consequence of donating gametes, gamete donors have a moral responsibility to care for the children they help create Fuscaldo Bayne argues that gamete donors are not parents because both causal and genetic accounts of parental responsibility suffer from a problem of regress, and thus fail as plausible grounds for parenthood Bayne
