Feng and Herbert (2006) concluded that 3PN embryos have 61.8% of triploid chromosome complement, 25.2% of mosaic arrangements, and only 12.65 of them had a diploid chromosome (22).

The Frequency of Chromosomal Euploidy Among 3PN Embryos

CHMs are purely androgenetic conceptions (only paternal genetic material is present) and usually diploid (2 paternal chromosome complements without a maternal chromosome complement) (16); most result from fertilization of an ovum devoid of maternal genetic material by a single sperm that duplicates (monospermy; ~85%), (17-19) but a subset is due to fertilization by 2 sperm (dispermy).

Hydatidiform Moles Ancillary Techniques to Refine Diagnosis

After detailed history and examination, the current approach is to (a) identify the sex chromosome complement by karyotype analysis or FISH with X and Y probes and chromosome microarray; (b) gather additional phenotypic information by complete metabolic and endocrine testing as well as imaging studies, and (c) genetic testing for copy number variants in regions associated with known DSD genes or gene sequencing either for single candidate gene or a gene panel.
