Table 1 Baseline demographic characteristics of 722 couples seeking IVF: median, standard deviation, missing data (MD), P value describing the difference between cannabis users and non-users including a subgroup analysis of the user group according to the identity of the user (female partner, male partner, or both). The data relates to the patient’s age and serum anti-Mullerian hormone (AMH) that represents the ovarian reserve at the time the IVF treatment was conducted
