The relationship between cannabis use and IVF outcome—a cohort study

Table 3 Treatment outcome for 722 IVF patients based on the level of cannabis use: implantation rate (IR) and ongoing pregnancy rate (OPR) among the different study groups as well as combining all users. The symbols in the first two rows define the level of use for the two partners: 0, no use; +, light use; ++, heavy use

Group	Level of use								All users

Female	0	+	++	+	++	0	0	+
Male	0	0	0	+	++	+	++	++
Number	654	13	2	5	4	26	14	4	68	P value
Implantation rate per embryo transfer	41.13%	53.85%	0	37.5%	50%	47.06%	27.8%	0	40.74%	0.45
Ongoing pregnancy rate per cycle started	29.10%	43.75%	0	42.86%	40.00%	40.0%	25.0%	0	35.23%	0.508

describes the rate of implantation per embryo transfer as well as the ongoing pregnancy rate per ovum pickup (OPU) among the different test groups: G1, non-users; G2, female light user partner non-user; G3, female heavy user partner non-user; G4, both female and male partners are light users; G5, both female and male partners are heavy users; G6, female non-user, male light user; G7, female non-user, male heavy user; and G8, female light user and male heavy user. No significant difference in either implantation or ongoing pregnancy rate was detected using the Kruskal-Wallis test
