High fishing intensity reduces females' sperm reserve and brood fecundity in a eubrachyuran crab subject to sex- and size-biased harvest
(2017)
Size-selective male fisheries may result in sperm limitation whereby the number of sperm is insufficient to fertilize all oocytes produced by females. In eubrachyuran crabs, females have seminal receptacles for sperm storage ...
Sperm biology of merluccius australis: sperm structure, semen characteristics and effects of ph, temperature and osmolality on sperm motility
(ELSEVIER SCIENCE BV, 2013)
In this article we describe basic aspects of the sperm biology of Merluccius australis, in particular assessing the effects of pH (6, 8 and 10), temperature (4, 10 and 15 degrees C) and osmolality (922 mOsm/kg, 822 mOsm/kg, ...

Differences in sperm migration through cervical mucus in vitro relates to sperm colonization ofthe oviduct and fertilizing ability in goats
(ELSEVIER SCIENCE INC, 2002)
Sperm migration in estrous cervical mucus can be used to measure the ability of spermatozoa to migrate through the genital tract, The relationship of this test with the sperm colonization of the isthmus, and its impact on ...
Gold-standard and improved framework for sperm head segmentation
(ELSEVIER IRELAND LTD, 2014)
Semen analysis is the first step in the evaluation of an infertile couple. Within this process, an accurate and objective morphological analysis becomes more critical as it is based on the correct detection and segmentation ...
