While long-term study is lacking, one case study suggests that tucking can affect fertility.
In a case study [1] of one transwoman, tucking resulted in oligospermia – an abnormally low sperm count – affecting fertility. Elevation of the testes because of tucking may contribute to heat stress and consequent impairment of spermatogenesis.
After cessation of tucking and the provision of a new sperm sample, the sperm count in the patient was improved, and the semen had increased opacification.
A further study [2] found that tucking could create a suboptimal environment for spermatogenesis.
