In vitro fertilization (IVF), using egg donation and surrogacy, is becoming a more common method of choice for same-sex male couples wishing to have families. This story is followed by a tribute to a late colleague, Dr Alec Roy. The next section presents twin research reviews of dog ownership, twinning rates in Awassi ewes, monozygotic male twins with mitochondrial encephalomyopathy, and a novel twin study of meditation. Several human-interest items capture other informative aspects of twinship. They include twins with unrelated biological parents, twins born in different years, a valedictorian-salutatorian pair; highlights from the Annual Twins Days Festival, an FBI identical twin identification dilemma, and a pair of identical twin doctors.","interpretation_basis":null,"fulltext_status":null,"interpretation":null,"fulltext":{"available":false,"status":null,"reason":"尚未抓取全文（未入选、分数未达阈值，或还没跑 fulltext 步骤）","pmcid":null,"license":null,"chars":0,"source":null,"fetched_at":null}}
