THE 2020 GORDON RESEARCH CONFERENCE ON MAMMALIAN REPRODUCTION WILL BE HELD AT MOUNT HOLYOKE COLLEGE IN SOUTH HADLEY, MASSACHUSETTS, FROM AUGUST 9-14, 2020. THIS CONFERENCE WILL FEATURE THE MOST RECENT SCIENTIFIC ADVANCES FROM ACROSS THE SPECTRUM OF REPRODUCTIVE BIOLOGY, TO INCLUDE GAMETOGENESIS, ENDOCRINE FUNCTION, OVARIAN AND TESTIS BIOLOGY, UTERINE FUNCTION, PLACENTATION, DEVELOPMENTAL BIOLOGY OF THE MALE AND FEMALE REPRODUCTIVE TRACTS, AND PARTURITION. THE SCIENCE WILL HIGHLIGHT BASIC, TRANSLATIONAL, AND CLINICAL RESEARCH THAT BRINGS ATTENTION TO THE REPRODUCTIVE, LIFE-LONG, AND TRANSGENERATIONAL HEALTH OF HUMANS AND ANIMALS, INCLUDING AGRICULTURALLY IMPORTANT SPECIES. WORK WILL FEATURE USE OF IN VITRO, IN VIVO, AND IN SILICO RESEARCH MODELS. SCIENTIFIC SESSIONS WILL INCLUDE MULTIDISCIPLINARY TALKS THAT CENTER AROUND A COMMON THEME, AND WHOSE CHAIR WILL SERVE AS A DISCUSSION LEADER THAT WILL PROMOTE INTERACTIVE DIALOGUE FROM THE AUDIENCE, WITH SPECIAL CONSIDERATION FOR SUPPORTING AND ENCOURAGING TRAINEE PARTICIPATION. SHORT TALKS SELECTED FROM SUBMITTED ABSTRACTS WILL BE PRESENTED, WITH AN EMPHASIS ON JUNIOR INVESTIGATORS AND TRAINEES. ALL ATTENDEES ARE ENCOURAGED TO PARTICIPATE IN THE "POWER HOUR", AN INFORMAL, DISCUSSION-BASED GATHERING THAT ADDRESSES THE CHALLENGES FACED BY WOMEN AND ALL SCIENTISTS AT VARIOUS STAGES OF THEIR CAREERS. BY INCORPORATING GROUP MEALS, UNSCHEDULED AFTERNOONS, AND A FUN SOCIAL PROGRAM, THE GRC ON MAMMALIAN REPRODUCTION OFFERS UNIQUE OPPORTUNITIES FOR NETWORKING AND SCIENTIFIC INTERACTIONS AMONG RESEARCHERS OF DIVERSE AND MULTI-DISCIPLINARY BACKGROUNDS WHO ARE AT ALL STAGES OF THEIR CAREERS.
