This review examines the place of mitochondria in the life cycle through oogenesis,
ovulation and early embryogenesis. Mitochondria are semi-autonomous organelles …

Using a semi-quantitative review of published electron micrographs, we have explored the
passage of mitochondria from one generation to the next through the cytoplasm of the …

OBJECTIVE: To correlate sperm mitochondrial respiratory efficiency with variations in sperm
motility and with sperm morphologic anomalies. METHODS: Sperm mitochondrial …

Mitochondria is a powerhouse organelle involved in ATP synthesis, calcium signaling,

Increasingly, mitochondria are being recognized as having an important role in fertility.
Indeed in assisted reproductive technologies mitochondrial function is a key indicator of …

The aim of this study has been to observe, by electron microscopy, the morphological
changes affecting mitochondria and associated organelles in the human female germ cell …

OBJECTIVE: To determine the content of sperm mitochondrial DNA (mtDNA) in patients with
asthenospermia or with poor sperm motility. DESIGN: Analysis of the content of mtDNA as …

Mammalian mitochondrial DNA (mtDNA) is a small, maternally inherited genome that codes
for 13 essential proteins in the respiratory chain. Mature oocytes contain more than 150 000 …

In this review we examine the present state of knowledge on male infertility, a problem that is
apparently increasing in industrialised societies. We examine the hypothesis that some …

To determine whether the outcome of in vitro fertilisation (IVF) is influenced by the
percentage of spermatozoa with functional mitochondria, a total of 91 random couples …
