| Treatment protocol |
Sibling male mice were split at weaning (3 weeks) onto control or low protein, or control or high fat diets. Mice were maintained on these diets until sacrifice at 10 weeks.

| Extraction protocol |
Cauda epididymis and vas deferens was rapidly dissected and punctured, and was incubated in 500 ¼L of human tubule fluid (HTF - Millipore MR-070-D) at 37 C for 30 minutes. Supernatant was removed, sperm were pelleted at 2000 g for 5 minutes, washed once with 1 mL water and then pelleted. Sperm were washed again with 1 mL PBS, and pelleted again. Sperm were resuspended in 400 ¼L DNA Lysis Buffer (10mM Tris, 5mM EDTA, 0.5% SDS, and 200mM NaCl) with 10mM DTT, and incubated at 37oC for 30 minutes. Sperm were subjected to needle homogenization. 20 ¼g/mL Proteinase K was added to the homogenate and incubated at 55oC for 16 hours. DNA was extracted with Phenol:Chloroform:Isoamyl Alcohol and precipitated with 100% EtOH.
DNA was sheared to an average length of ~100-500 bp with a Covaris sonicator, fragment ends were cleaned up and A-tailed. Fragments were ligated to pre-methylated Illumina paired-end adaptors, bisulfite converted, and PCR-amplified.
