A molecular approach on sperm changes during epididymal maturation, ejaculation and in vitro capacitation of boar spermatozoa 

Fàbrega Coll, Anna (Date of defense: 2012-07-20)

Mammalian spermatozoa acquire functionality during epididymal maturation and ability to penetrate and fertilize the oocyte during capacitation. Sperm quality results indicated that both epididymal maturation and ejaculation ...

Aquaporins in boar and bull spermatozoa: identification and functional implications 

Prieto Martínez, Noelia (Date of defense: 2017-03-17)

Aquaporins (AQPs) are proteins involved in the transport of water and some other solutes across plasma membranes. The fact that mammalian spermatozoa are highly permeable to water suggests the presence of these proteins. ...

Freezability markers for boar sperm: new proteomic approaches 

Vilagran Martí, Ingrid (Date of defense: 2016-02-05)

Sperm cryopreservation is currently the most suitable technique to store boar sperm samples for a long period of time. However, not all boar ejaculations present the same freezability, this allows the classification of ...

Molecular insights into mammalian sperm physiology: a comparative study of glutathione S-transferases in male reproduction 

Llavanera Bruguera, Marc (Date of defense: 2023-05-12)

Male infertility is a global health problem affecting one in four infertile couples. This also has a negative repercussion on the animal breeding industry, where infertility has a detrimental impact on their balance sheets. ...

Relevance of sperm chromatin protamination, condensation and DNA integrity for sperm function and fertility: the role of toroid linker regions 

Viñolas Vergés, Estel (Date of defense: 2023-07-27)

Male fertilising capacity has traditionally been predicted by the assessment of sperm concentration, motility and morphology. During the last few decades, however, research has been particularly focused on the analysis of ...
