reproductive system

absent oocytes ( J:278517 )

• by 8 months

abnormal chromosomal synapsis ( J:278517 )

• a large number of autosomes remain unsynapsed in spermatocytes and display impaired meiotic recombination

abnormal female meiosis ( J:278517 )

• delayed meiosis prophase I

• however, prophase I is successful

decreased mature ovarian follicle number ( J:278517 )

• at 6 months

abnormal ovarian folliculogenesis ( J:278517 )

• reduced follicle pool and premature ovarian insufficiency

absent mature ovarian follicles ( J:278517 )

• at around 8 months of age

• however, ovary morphology is normal up to mid-adulthood

small testis ( J:278517 )

abnormal spermatogenesis ( J:278517 )

azoospermia ( J:278517 )

• lack postmeiotic spermatocytes in the seminiferous tubules

• no spermatozoa in the epididymis

arrest of male meiosis ( J:278517 )

• spermatocytes fail to process beyond pachytene

female infertility ( J:278517 )

• after mid-adulthood

male infertility ( J:278517 )

homeostasis/metabolism

abnormal double-strand DNA break repair ( J:278517 )

• in spermatocytes
