Mitochondrial DNA content and 4977 bp deletion in unfertilized oocytes

Previous studies analysing the incidences of mitochondrial DNA (mtDNA) deletions and mtDNA content in unfertilized oocytes in relation to donors' age have been controversial. The objective of the study was to compare these two parameters in unfertilized oocytes and relate them to the donors' age. Fifty-two women donated 155 unfertilized metaphase II (MII) oocytes. The incidence of 4977 bp deletion was 34.6%, and the mtDNA copy number was 598 350 ± 265 862. Women ≥35 years of age had a significantly higher incidence of 4977 bp deletion, lower mtDNA copy number, higher FSH level and poorer ovarian response when compared with younger women. The mtDNA copy number was negatively correlated with the donor's age. The higher incidence of mtDNA deletion and lower mtDNA copy number in older women suggested that these two parameters may reflect ovarian ageing. © 2005 Oxford University Press.link_to_subscribed_fulltex

Molecular analysis of the androgen receptor gene in Hong Kong Chinese infertile men

Purpose: To investigate the relationship between CAG repeat length in the androgen receptor gene and impaired spermatogenesis in Hong Kong Chinese population. Methods: The CAG repeat region was amplified by polymerase chain reaction (PCR) in 85 nonobstructive azoospermic or severe oligozoospermic men, and 45 fertile males. The number of CAG repeat was analyzed by DNA sequencing. Serum FSH, LH, and testosterone levels were also determined in these men. Results: Among nonobstructive azoospermic males, three men (5.7%) possessed short CAG repeats (30). Short CAG repeats (<16) were also found in two severe oligozoospermic males (6.3%). The incidence of infertile men with short or long CAG repeats is significantly higher in the azoospermic group (p = 0.03) but not in the severe oligozoospermic group (p = 0.17) when compared with the fertile controls. Conclusion: Our data suggest an association between CAG repeat lengths and impaired spermatogenesis in azoospermic males in our population.link_to_subscribed_fulltex

Mitochondrial DNA deletion in granulosa and cumulus oophorus cells

The incidence of the 4,977-bp deletion in mitochondrial DNA (ΔmtDNA4977) in 73 pairs of granulosa and cumulus oophorus cells was studied with polymerase chain reaction (PCR), and was significantly higher in granulosa cells (GC) (67/73, 91%) than in cumulus oophorus cells (17/73, 23.3%), independent of the donors' age. In the cumulus oophorus cells, the oocyte morphology, the ooplasma diameter, and the proportion of oocytes fertilized normally were comparable between those with and without ΔmtDNA4977; whereas the oocyte diameter and the zona thickness were significantly higher in those with ΔmtDNA4977. ©2006 by American Society for Reproductive Medicine.link_to_subscribed_fulltex
