A '''xenogerm''' is a specialized organ used to change the [[Xenotypes|xenotype]] of a pawn.

== Acquisition ==
Xenogerms are created at a [[gene assembler]] by combining the [[genes]] from [[genepack]]s stored in nearby [[gene bank]]s. Creating a xenogerm is considered a form of research, and requires the [[Skills#Intellectual|intellectual]] skill. The actual time to create a xenogerm depends on the genes it contains {{Check Tag|Check|How do genes affect recombination time? What about skill?}}

Normally, xenogerms can be created for free. However, if they contain any archite genes, then the required number of [[File:Archite capsule required.png|16px|Archite Capsules]][[archite capsules]] will need to be provided before gene recombination can begin.

== Summary ==
The purpose of a xenogerm is to change the xenotype of the pawn it is installed into. This is done through an implantation surgery. The effects of xenogermination are instant, and will change the affected pawn upon the surgery's completion.

Xenogerms require a minimum metabolic efficiency of -5. Pawns cannot receive xenogerms that would lower their efficiency below this value.

Xenogerms can only add xenogenes to a pawn, meaning that their effects will not be inherited by children.

[[File:Gizmo xenogerm order implantation.png|75px|thumb|left]]
Since each xenogerm is unique, its implantation must be ordered manually. There are three ways to do this:
* Select the xenogerm. Click on the "Order implantation" gizmo. Select the desired patient from the list.
* Select your patient. Right-click the xenogerm, then click "Order implantation".
* Select your patient. Open their health tab, then view their queued surgeries. Select "Add bill", then choose "Implant xenogerm". Choose the desired xenogerm from the list that appears.

Once the bill is ready, a doctor will need to perform the implantation surgery. The operation requires 4 medicine of [[Herbal medicine|herbal quality]] or higher, and requires {{ticks|2000}} of work.

After implantation is complete, the patient will enter a "xenogermination coma". This lasts about 2 days, depending on the quality of the surgery, and will cause a total inability to move. See the section below on more details on how this time is calculated.

In addition, the patient's genes will need between {{Ticks/gametime/years|6000000}} and {{Ticks/gametime/years|8400000}} to regrow. Extracting their genes with a [[gene extractor]] during this time will kill them. However, it is safe to implant another xenogerm during this time.

Multiple xenogerms can be implanted into the same pawn. However, each new xenogerm will overwrite the effects of the last. In other words, if the pawn has xenogenes not contained in the new xenogerm, then they will always be removed. This includes archite genes, which effectively means that any archite capsules previously spent on the pawn will be destroyed entirely.

==== Breakdown of Xenogermination Time ====
There are a number of factors and specific effects on xenogermination time, which the list below will break down.

<div class="mw-collapsible-content">
* The time spent in a xenogermination coma depends on the quality of the surgery, clamped within 0% and 100%
** At 0% quality, the duration will be 3 days
** At 100% quality, the duration will be 1 day
** This means that the duration in days can be found with the equation: 3 - (Quality × 2)
* The quality of the surgery depends on the following factors:
** The surgery has a base quality of 100%
** Multiplied by the [[medical surgery success chance]] of the surgeon.
** Multiplied by the [[surgery success chance factor]] of the patient's bed.
** Doubled if the doctor has an [[inspired surgery]]
** Multiplied by the [[medical potency]] of the medicine used, based on a <abbr title="piecewise linear">simple</abbr> curve.
*** x0.7 at 0% potency, x1 at 100% potency, x1.3 at 200% potency
*** 88% for [[herbal medicine]] (60% potency)
*** 100% for [[Medicine|industrial medicine]] (100% potency)
*** 118% for [[glitterworld medicine]] (160% potency)
** Multiplied based on the overall complexity of the xenogerm
*** Factor starts at 100% at 0 complexity
*** -2% for each point of complexity
*** Minimum factor of 60%, at 20 points of complexity
** Multiplied based on patient's age
*** 100% up to age 20
*** -1.25% for each year after 20
*** Minimum of 50% at the age of 60
