Using online platforms to offer or seek sperm donation: A systematised narrative review of donor and recipient...

Online sperm donation (OSD) is reshaping donor conception by enabling direct connections between donors and recipients outside clinical settings. This systematised narrative review triangulates existing research on sperm donors and recipients who connect through OSD platforms, comparing their perceptions and experiences across different stages of the donation process. By exploring the complex interplay between donors' and recipients' motivations, it fosters dialogue between research areas often examined in isolation. Studies show that donors and recipients, who often explore alternatives alongside OSD, turn to this option to establish contact, gain flexibility, and sometimes facilitate a relationship between the donor and the child. Donors are primarily motivated by altruism or the desire to transmit their genetic heritage, while recipients often turn to OSD for its affordability and flexibility. Both parties engage in negotiations regarding expectations, insemination methods, and future contact, with both parties assessing trust and compatibility. While many report positive experiences, some-especially recipients-face challenges such as communication difficulties, unsolicited advances or sexual misconduct. In the absence of regulation, recipients bear the burden of managing risks related to safety and donor reliability, whereas donors are mainly concerned with legal parentage. Donors and recipients also differ on the donor's role in the child's life, ranging from no involvement to ongoing contact, with post-conception agreements sometimes evolving. Further research is needed to address key gaps, particularly long-term post-conception experiences and perspectives of recipients and online-donor-conceived individuals. This review highlights that rather than eliminating OSD, policies should prioritise safety, transparency, and informed decision-making while expanding access to fertility clinics and establishing a clear legal framework. A balanced approach-one that respects autonomy while mitigating risks-will be essential to fostering ethical and sustainable donor-recipient arrangements, ensuring positive outcomes, especially for recipients and their families.
