(a) (Adapted from Araki et al. [27]) Hollow-core agarose capsule (outer diameters, 80–120 μm; inner diameters, 60–100 μm) held by a holding pipette before injection. (b) (Adapted from Tomita et al. [28]) The needle was inserted into the hollow hyaluronan-phenolic hydroxyl microcapsules and one spermatozoon was slowly released. The average diameter of capsules was 241.6 ± 30.4 μm and thickness of the HA membrane was 29.6 ± 7.2 μm (N = 38). Scale bars = 20 μm
