Plus-minus values can be indicated by means ± SD. No significant intergroup differences existed in baseline characteristics (p > 0.05). FSH, follicle-stimulating hormone; LH, luteinising hormone; T, total testosterone; E2, oestradiol; AMH, anti-Müllerian hormone; IVF, in vitro fertilization; ICSI, intracytoplasmic sperm injection.
BMI, body mass index can be calculated as the weight (kilograms) divided by the square of height (meters).
Data are number/total number or number (%) unless stated otherwise.
