he should chant.
One observing the vow of celibate brahmacārī life should never pass semen. If the semen by chance spills out by itself, the brahmacārī should immediately take bath in water, control his breath by prāṇāyāma and chant the Gāyatrī mantra.

Translation
One observing the vow of celibate brahmacārī life should never pass semen. If the semen by chance spills out by itself, he should take bath in water, control his breath by prāṇāyāma and chant the Gāyatrī mantra.
He should not intentionally expel his semen. If it happens by chance, he should bathe and then do prāṇāyāma and chant the Gāyatrī mantra.
