What this card shows
The Donor gamete use by month card shows how often donor eggs and donor sperm were used, as a share of the fertilizations your laboratory carried out each month. Gametes are the eggs and sperm themselves.
There are two lines:
Donor eggs (%): the share of the month's fertilizations using donor eggs.
Donor sperm (%): the share using donor sperm.
The underlying counts, Fertilizations, Donor eggs and Donor sperm, are columns on the card rather than lines, so a quiet month can be checked by hovering rather than by adding a second axis.
Reading the card
Both Anonymous donor and Known donor count as donor. Eggs or sperm provided by the patient or their partner do not.
The denominator is every fertilization carried out that month, whatever its gamete sources. So the two lines are shares of the same base and can be read against each other directly.
A cycle with no provider recorded still counts towards the denominator, but can never count as donor. A month where providers have not been filled in will therefore show a lower donor share than it should. If a line drops unexpectedly, the Fertilizations table below this chart will show whether the source columns are populated for that month.
The two lines are independent. A cycle using both donor eggs and donor sperm counts on both.
Hover any point to read the exact shares and the counts behind them.
The card sits on the PGT KPIs dashboard, on the Procedure mix tab, and responds to the three fertilization filters at the top:
Procedure date: the time window. It scopes by the date the procedure was performed, and starts on the past 6 months plus the current month.
Performed by (fertilization): narrow to one practitioner's work.
Clinic (patient's cycle location): focus on one or more of your locations.
The Biopsy date, Embryologist (biopsy), Destination lab and Test types filters belong to the biopsy cards and leave this chart alone.
Clinic (patient's cycle location) is the clinic the patient's cycle belongs to, not the laboratory that carried out the procedure. wawa does not record which laboratory performed the work.
Where this data comes from
Gamete sources are not recorded on the fertilization itself. They come from the Gametes tab of the patient's Cycle page, where each cycle's oocyte provider and sperm provider are added and marked as the patient, the partner, a known donor or an anonymous donor.
Every fertilization in a cycle inherits that cycle's sources, so setting the providers once at the start of the cycle is what makes this chart work. Where a cycle records more than one provider for a gamete, the first is the one used.
Opening this card
In wawa, open Insights from the sidebar, then go to Standard Reports → Laboratory Performance - Biopsies/PGT → PGT KPIs. Select the Procedure mix tab. The Donor gamete use by month card is the lower left of the four charts at the top of the tab.
