In the full Narada Purana (Purva Bhaga) this is chapter 55, verse 55.
Seen by Mars, or in a male navamsha (one-ninth part of a sign), they give a neuter birth. Venus and the Moon may be in even signs. Mercury, Mars, the lagna (rising sign) and Jupiter may be in odd signs, seen by male planets. (Our text is unclear here: a word in the first line reads 'daughter'.)
Simple meaning: Some placements seen by Mars give a neuter birth. Venus and Moon in even signs begin a twin rule.
लग्नेंदुसमगौ युग्मस्थाने वा यमलंकराः ।
The lagna and the Moon in even signs can give twins.
त्रितयं ज्ञांशकाद्युग्मममिश्रैः सममादिशेत् ।
Mercury's sight can give three at one birth. A lagna late in Sagittarius begins a rule for many.
वीर्याढ्यज्ञार्किसदृष्टैः कोशस्थावहवोगिनः ।
Strong Mercury and Saturn can give many in one birth. The ten womb months each have a planet lord.
