After retrieval, the ova are fertilized by the sperm of the male partner (or sperm donor) in the laboratory, and, after several days, the best resulting embryo(s) is/are placed in the uterus of the recipient, whose uterine lining has been appropriately prepared for embryo transfer beforehand. The recipient is usually, but not always, the person who requested the service and then will carry and deliver the pregnancy and keep the baby. The egg donors process in detail
Before any intensive medical, psychological, or genetic testing is done on a donor, they must first be chosen by a recipient from the profiles on agency or clinic databases (or, in countries where donors are required to remain anonymous, they are chosen by the recipients doctor based on their physical and temperamental resemblance to the recipient woman). This is due to the fact that all of the mentioned examinations are expensive and the agencies must first confirm that a match is possible or guaranteed before investing in the process. Each egg donor is first referred to a psychologist who will evaluate if she is mentally prepared to undertake and complete the donation process. These evaluations are necessary to ensure that the donor is fully prepared and capable of completing the donation cycle safely and successfully.
Long face syndrome, also referred to as skeletal open bite, is a relatively common condition characterised by excessive vertical facial development. Its causes may be either genetic or environmental. Long face syndrome is "a common dentofacial abnormality. ": 369   Its diagnosis, symptomology and treatments are complex and controversial. Indeed, even its existence as a "syndrome" is disputed. Definition and treatment
One dental textbook defines it as: "Dolicofacial, there is excess of lower facial height usually associated with lower occlusal and mandibular plane angles." This is often associated "with vertical maxillary excess and mandibular hypoplasia." Luc P. M. Tourne, a Fellow in the Department of TMJ and Craniofacial Pain at the University of Minnesota School of Dentistry, noted: "There is a clinically recognizable facial morphology, the long face syndrome, which has been incompletely described in the literature,"  However, her study of 31 adults with this syndrome, which included "analysis of esthetics, skeletal morphology, and occlusion" confirmed "this basic dentofacial deformity" has associations " with excessive vertical growth of the maxilla." She reported that "closed bite" and "dental open" are two of the syndromes variants.The treatment for young patients troubled by long face syndrome is to halt and control descent of the lower jaw and to prevent the eruption of posterior teeth. In severe cases of deformity, a mixture of orthodontics and orthognathic surgery may be the only effective solution. The long-term (more  than 6 years) effectiveness of surgical treatments for long face syndrome has been subject to study.
