Netflix released all five episodes of Sex, Explained on January 2, 2020. The documentary limited series was produced by Vox, narrated by Janelle Monáe, and holds a 10.0/10 critical score, with Rotten Tomatoes at 100%.
It is a spin-off of Explained and a sibling to The Mind, Explained. Each episode takes one subject and works it over, with the aim of explaining nuances and trends rather than settling arguments.

Five Episodes, One Afternoon
The run is short. One season, five episodes, all released the same day. That structure is the show’s smartest decision. There is no weekly drip, no mid-season lull, no episode ordered to fill a slot. Five is enough to establish a method and not enough to wear it out.
A viewer can finish Sex, Explained in a single sitting. That matters for a documentary about a subject most people learn about in fragments, from friends, from school lessons that skip the useful parts, from the internet at its least reliable. The show’s format meets that problem directly: pick a topic, explain it, move on.
Janelle Monáe Takes the Narrator’s Chair
Monáe is credited as Self — Narrator. That is the whole cast listing, and it is the right one.
A narrator carries a documentary like this. The show is built on a voice guiding a viewer through biology, history and social change without lecturing.
Monáe’s presence does real work. The tone lands closer to a smart friend walking you through a subject than a classroom. That is the register the show needs.
Vox Built a Franchise and Kept It Tight
Sex, Explained is a Vox production, spun off from Explained alongside The Mind, Explained. That lineage is visible in the approach: take a broad subject, break it into parts, resist the urge to make each part an hour long.
The subject justifies the split. Sex carries its own history, its own science, its own politics, and the show treats those as separate rooms rather than one muddy pile.
What the Show Gets Right
The synopsis promises an entertaining and enlightening series about the ins and outs of sex. Both halves of that promise get kept, and the balance is the achievement.
Sex, Explained treats curiosity as reasonable. The biology of attraction and the history of birth control are not soft topics. They are the topics people actually want explained and rarely get explained well.
Five episodes is a statement of confidence. The show does not pad.
The Case Against the Perfect Score
A 10.0/10 invites skepticism, and the case against it is worth stating plainly. Five episodes cannot cover everything. A viewer who comes to Sex, Explained wanting depth on any single subject will leave wanting more. The show explains nuances and trends; it does not exhaust them. That is a limit, not a flaw, but it is a limit.
The other objection is structural. A limited series that arrives all at once and runs five episodes raises a fair question about what counts as a season of television. It does not change what the show does.
Neither objection survives contact with the actual episodes. The score reflects what the show set out to do and how completely it did it, not how long it ran.

Six years on, the source material offers no word on how the show is received now, and this paper will not supply one. What the record does give is a completed project: five episodes, one narrator, one release day, a 100% score on Rotten Tomatoes and a 10.0/10.
The part worth watching is the decision to stay brief. Five episodes is a small order for a streaming documentary, and Sex, Explained filled it without reaching for more. That is the whole case for the score.
