# Reproduction & genetics lifecycle

> The full chain from intimacy to a new character: fluids, fertility, conception, pregnancy, birth, and inheritance.

The full chain from intimacy to a new character: fluids, fertility, conception, pregnancy, birth, and how a child inherits its traits and species.

## The life-cycle at a glance

1. **Fluids are exchanged.** During an intimate scene, reaching a climax can transfer fluids from one character to another.
2. **Fertility matters.** A carrier can become fertile on a cycle. When a fertile carrier receives the right fluids in the right place, conception may happen — it's a chance, not a certainty, and the odds depend on how compatible the partners are.
3. **Pregnancy begins.** If conception succeeds, the carrier becomes pregnant. The pregnancy grows over time and can be tracked.
4. **Birth.** When the pregnancy reaches term, the carrier gives birth. Depending on the species, this may be a live birth or an egg that hatches later.
5. **A new character is born.** The child inherits traits from **both** parents — its body form, lineage, and a blended **species makeup**. That child can be raised, named, and even adopted.

## Where things land

Your character's real anatomy decides where a deposit actually goes and whether it can lead to a pregnancy. If a spot can't carry, the deposit simply passes through without conceiving. This keeps outcomes believable regardless of appearance.

## Fertility, cycles, and control

* Carriers ovulate on a cycle; there's a fertile window when conception is possible.
* You can influence fertility with in-world consumables — for example items that boost fertility, and items that prevent conception. Barrier items reduce the chance of fluids reaching a fertile spot at all.
* You are always in control: you choose whether to pursue conception, and content limits and consent apply throughout.

## Inheriting a species

A child's **species makeup** is a blend of its parents' makeups. Purebred parents tend to produce purebred children of the same species; mixed parents can produce **hybrids**. How the blend works — and how "how compatible are we?" is calculated — is explained in [Species compatibility](/system-guide/species-compatibility) and [Creating a species](/system-guide/creating-a-species).
