The START clinic feasibility study: exploring the feasibility of prospective obstetric research with retrospective Artificial Reproductive Technologies (ART) data linkage; dataset

The START clinic study recruited 120 participants conceiving by assisted reproductive technologies or spontaneous conception (fresh embryo transfer in-vitro fertilisation (IVF) N=36, frozen embryo transfer N=62, spontaneous conception N=14, ovulation induction N=7). These participants were prospectively observed 4-6 weekly throughout pregnancy, with retrospective linkage to fertility treatment data where possible. The feasibility assessment explored acceptability, possibility and extent of retrospective data access as well as recruitment, retention and acceptability of research measures and observation. This dataset includes all data used for analysis and publication of articles associated with The START clinic study.
