# How to: Embryo Transfers

With CRIOONLINE you can control the whole of your Embryo Transfer program.

### Step 1 - Inseminating the Donor mare

> Go to the Donor mare's profile and record a Breeding Service.
> 
> You can do it in 2 ways:
> 
> -   use the "**Mare's pregnancy status"** on the profile page ("Change status" button).
> -   or on the Breeding tab, adding a Breeding Service
> 
> In both cases, you have to mark the field "To be flushed" in YES. This will tell the system that this insemination is for embryo retrieval in 7-9 days.

### Step 2 - Recording the embryo flush

> After the 7-9 days, you will need to record the embryo flush on the Donor page.
> 
> To do so, go back to the  "**Mare's pregnancy status"** on the profile page (this time use the "Enter flush details" button).
> 
> When you record the embryo flush as successful, the system will redirect to the list of Breeding Services of the mare.  The donor mare will be open again.

### Step 3 - Transfer the embryo to the recipient mare

> Once you landed on the Breeding Services of the Donor mare, you will see a green button "FLUSH DONE". If you click it, you will see the option to record the embryo transfer on the recipient mare.
> 
> The system will list empty recipient mares for you to select from, and in case it is not yet created you can use the "+" button to create one on the fly. Remember that for a mare to be considered a Recipient and appear on the list, you should have marked it as so in the "Horse Status" section.
> 
> So, once you create this embryo transfer on the recipient, it will be marked as served but yet to be pregnancy checked.

**Take into account this:**

When starting to use the system, you may have several recipient mares already carrying a pregnancy.

Instead of going through the 3-step process detailed above, you can just record a Breeding Service on the Recipient mare of type "Embryo Transfer".  This way you don't have to enter so much historic information.
