Animal Conservation, EarlyView.Reproductive success rates are a key parameter determining the recovery potential of ex‐situ managed threatened species, with high rates often being required to produce offspring for wild releases while ensuring ex situ population viability. Here, we quantify reproductive success rates in the Extinct in the Wild sihek (Guam kingfisher) and find ...

Australian and New Zealand Journal of Obstetrics and Gynaecology, EarlyView.ABSTRACT Background Intracytoplasmic sperm injection (ICSI) was first developed to overcome male factor infertility. ICSI has increased in uptake globally, including in cases where its use is non‐essential for fertilisation. Aims To identify temporal trends in the use of, and indications for ICSI in an Australian context.

Non-Sinusoidal Bending Waves of Sperm Flagella [PDF]
, 1965 The analyses of flagellar movement stimulated by Sir James Gray's (1955) photographic study of the movement of sea-urchin spermatozoa have used sine waves as a convenient mathematical model for the active bending waves of flagella.

Effects of antibodies against dynein and tubulin on the stiffness of flagellar axonemes [PDF]
, 1981 Antidynein antibodies, previously shown to inhibit flagellar oscillation and active sliding of axonemal microtubules, increase the bending resistance of axonemes measured under relaxing conditions, but not the bending resistance of axonemes measured ...

The use of deidentified organ donor testes for research
Andrology, EarlyView.Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

The absence of both RIBC1 and RIBC2 induces decreased sperm motility and litter size in male mice
Andrology, EarlyView.Abstract Background RIBC1 (RIB43A domain with coiled‐coils 1) and RIBC2 (RIB43A domain with coiled‐coils 2) are homolog proteins of RIB43a which is localized to microtubules in the cilia and flagella of unicellular organisms. Cryo‐electron microscopy and artificial intelligence studies showed that RIBC1 and RIBC2 are microtubule inner proteins (MIPs ...
