What this card shows
The Donor sperm: stock for the six most-used characteristic combinations card shows how much donor sperm you hold for the six combinations of skin tone, hair color and eye color that your recipients have used most over the last 12 months. Each bar is one combination, written as skin tone / hair color / eye color (for example Light Fair / Brown Dark / Blue), and its length is the number of donor sperm devices, straws and vials, in storage today for donors with that combination.
The six combinations are chosen by use, not by stock. The card counts the devices thawed for treatment over the last 12 months, the current month and the 11 before it, and keeps the six combinations with the most. A combination your recipients use that you hold little or none of stays on the list, with a short bar or no bar at all, so the gap is visible.
A device counts as donor material when it is recorded as donated: its Freeze purpose is Donation or Known donation, or its Use status is Donation or Donated to bank. A donor's own samples, frozen for their own future treatment, are not counted. A device stays in stock until it is thawed or shipped out to another clinic.
Where a characteristic is missing from a donor's profile, that part of the combination reads Not recorded. If few of your donors have their characteristics recorded, Not recorded / Not recorded / Not recorded can be one of the six, or the only one.
Reading the card
The combinations run from the most used down. A combination with no stock has no bar.
Hover over a bar to see its number of devices in stock, the number of donors behind them (donors), and the number of devices used in the last 12 months (used_in_last_12_months).
The stock is always a snapshot of today. The dashboard's Date filter does not change it, and the 12 months used to choose the six are fixed, so this card and the Donor sperm: use of the six most-used characteristic combinations card next to it always show the same six combinations.
The Clinic filter narrows both the stock and the use that picks the six to the clinics you choose. Here, clinic means the site the storage tank belongs to.
Where this data comes from
The characteristics come from the donor's profile in wawa. Open the donor from Cryostorage → Donors and choose the Profile tab in the panel on the right: the Physical section shows Eye Colour, Hair Colour and Skin Colour.
To record or change them, choose Edit on the donor page and set the three fields under Physical Characteristics. The card capitalizes each word of a value, so Brown dark in the app appears as Brown Dark on the card.
The use that picks the six comes from thaws recorded with Treatment as the Reason. The stock comes from the donor's cryostorage records, listed on the Cryo Storage tab of the donor page.
Opening this card
In wawa, open Insights from the sidebar, then go to Standard Reports → Donor → Donor and choose the Sperm tab. The Donor sperm: stock for the six most-used characteristic combinations card is on the left, below the eye color cards, next to Donor sperm: use of the six most-used characteristic combinations.
