What this card shows
The Donor sperm: use of the six most-used characteristic combinations card shows how many donor sperm devices were thawed for treatment each month for the six combinations of skin tone, hair color and eye color that your recipients have used most. Each line is one combination, written as skin tone / hair color / eye color (for example Light Fair / Brown Dark / Blue).
The six are the same as on the Donor sperm: stock for the six most-used characteristic combinations card next to it. Both cards choose them by the number of devices thawed for treatment over the last 12 months, the current month and the 11 before it, so you can read each combination's use against the stock you hold.
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. Only devices thawed with the reason Treatment count. Thaws for any other reason, such as a test thaw, research or a discard, are not counted.
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
Each point is one month, by the date of the thaw. Hover over a point to see how many devices were thawed that month.
A line joins only the months that had thaws, so a straight stretch between two points does not mean there were thaws in the months between.
The dashboard's Date filter sets the months shown. By default it covers the last 12 months, including the current month. It does not change which six combinations are shown: those are always chosen from the last 12 months.
The Clinic filter narrows the count, and the use that picks the six, to the clinics you choose. Here, clinic means the site the storage tank belongs to, so a device counts toward the clinic where it was stored before it was thawed. The Donor sperm used in treatment card at the top of the tab uses the site the treatment cycle ran at instead, so with a clinic selected the two can differ.
Long combination names are shortened in the legend. To read them in full, open the card by clicking its title and switch to the table view.
Volumes per combination are small, so read the shape over several months rather than reacting to a single one.
Where this data comes from
A device is used when staff thaw it in wawa with Treatment as the Reason. Thaws are recorded with Thaw on the sample's page, and a treatment thaw is linked to the recipient's cycle. The thaw's record shows its Reason and, under Consumer cycle, the cycle it was used for. The month on the card comes from the thaw's Thawed at date.
The characteristics come from the donor's profile. 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.
If a thaw is missing from the card, check that its Reason is Treatment and that the device's Freeze purpose or Use status is a donation value.
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: use of the six most-used characteristic combinations card is on the right, below the eye color cards, next to Donor sperm: stock for the six most-used characteristic combinations.
