{"cited_by_count":3621847,"description":"This cluster of papers focuses on male infertility, reproductive health, and the underlying factors affecting sperm quality and testicular function. It covers topics such as sperm DNA fragmentation, oxidative stress, spermatogonial stem cells, and the role of androgen receptors in spermatogenesis. Additionally, it explores trends in fertility and the impact of environmental and genetic factors on male reproductive disorders.","display_name":"Sperm and Testicular Function","domain_id":"4","external_ids":{"openalex":"https://openalex.org/T10116","wikipedia":"https://en.wikipedia.org/wiki/Male_infertility"},"field_id":"27","id":"T10116","keywords":[{"display_name":"male infertility","id":"male-infertility","score":0.6391,"url":"https://openalex.org/keywords/male-infertility"},{"display_name":"sperm motility","id":"sperm-motility","score":0.7458,"url":"https://openalex.org/keywords/sperm-motility"},{"display_name":"spermatogenesis","id":"spermatogenesis","score":0.5597,"url":"https://openalex.org/keywords/spermatogenesis"},{"display_name":"semen quality","id":"sperm-quality","score":0.68,"url":"https://openalex.org/keywords/sperm-quality"},{"display_name":"sperm cryopreservation","id":"sperm-cryopreservation","score":0.7373,"url":"https://openalex.org/keywords/sperm-cryopreservation"},{"display_name":"testis","id":"testis","score":0.3805,"url":"https://openalex.org/keywords/testis"},{"display_name":"sperm morphology","id":"sperm-morphology","score":0.736,"url":"https://openalex.org/keywords/sperm-morphology"},{"display_name":"male fertility","id":"male-fertility","score":0.5557,"url":"https://openalex.org/keywords/male-fertility"},{"display_name":"sperm viability","id":"sperm-viability","score":0.7966,"url":"https://openalex.org/keywords/sperm-viability"},{"display_name":"spermatozoa","id":"spermatozoa","score":0.5497,"url":"https://openalex.org/keywords/spermatozoa"},{"display_name":"Sertoli cells","id":"sertoli-cells","score":0.612,"url":"https://openalex.org/keywords/sertoli-cells"},{"display_name":"sperm concentration","id":"sperm-concentration","score":0.7298,"url":"https://openalex.org/keywords/sperm-concentration"},{"display_name":"sperm capacitation","id":"sperm-capacitation","score":0.8043,"url":"https://openalex.org/keywords/sperm-capacitation"},{"display_name":"epididymis","id":"epididymis","score":0.5153,"url":"https://openalex.org/keywords/epididymis"},{"display_name":"varicocele","id":"varicocele","score":0.6379,"url":"https://openalex.org/keywords/varicocele"},{"display_name":"seminal plasma","id":"seminal-plasma","score":0.5911,"url":"https://openalex.org/keywords/seminal-plasma"},{"display_name":"Leydig cells","id":"leydig-cells","score":0.5036,"url":"https://openalex.org/keywords/leydig-cells"},{"display_name":"semen analysis","id":"semen-analysis","score":0.7411,"url":"https://openalex.org/keywords/semen-analysis"},{"display_name":"azoospermia","id":"azoospermia","score":0.606,"url":"https://openalex.org/keywords/azoospermia"},{"display_name":"intracytoplasmic sperm injection","id":"intracytoplasmic-sperm-injection","score":0.2568,"url":"https://openalex.org/keywords/intracytoplasmic-sperm-injection"},{"display_name":"semen parameters","id":"semen-parameters","score":0.7768,"url":"https://openalex.org/keywords/semen-parameters"},{"display_name":"seminiferous tubules","id":"seminiferous-tubules","score":0.6288,"url":"https://openalex.org/keywords/seminiferous-tubules"},{"display_name":"sperm count","id":"sperm-count","score":0.6063,"url":"https://openalex.org/keywords/sperm-count"},{"display_name":"acrosome reaction","id":"acrosome-reaction","score":0.7912,"url":"https://openalex.org/keywords/acrosome-reaction"},{"display_name":"semen extenders","id":"semen-extenders","score":0.8418,"url":"https://openalex.org/keywords/semen-extenders"}],"legacy_keywords":["Sperm DNA Fragmentation","Oxidative Stress","Spermatogonial Stem Cells","Testicular Function","Reproductive Hormones","Sperm Quality","Germ Cell Development","Androgen Receptor","Semen Analysis","Fertility Trends"],"openalex_id":"https://openalex.org/T10116","source_created_date":"2024-01-23T15:27:05","source_updated_date":"2026-10-17T03:02:00","subfield_id":"2743","url":"/topics/T10116","works_api_url":"https://api.openalex.org/works?filter=topics.id:T10116","works_count":237911,"label":"Sperm and Testicular Function","provider":"openalex","revision":"6cbcabfdfde484e2","taxonomy_revision":"f050b5d4780b1289","title":"Sperm and Testicular Function","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36108824075447654","address_version":"morton4x16-v1","coordinates":[4,27,2743,10116],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
