Exempel på hur du använder SPERM i en mening

• In plants and animals, an embryo develops from a zygote, the single cell that results when an egg and sperm fuse during fertilization.
• The book is centered on the sailor Ishmael's narrative of the maniacal quest of Ahab, captain of the whaling ship Pequod, for vengeance against Moby Dick, the giant white sperm whale that bit off his leg on the ship's previous voyage.
• In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male sperm cell.
• Originally discovered in 1900 by Alberto Ascoli, it was isolated by hydrolysis of yeast nuclein; it was also found in bovine thymus and spleen, herring sperm, and wheat germ.
• Eukaryotic flagella found on sperm cells and many protozoans have a similar structure to motile cilia that enables swimming through liquids; they are longer than cilia and have a different undulating motion.
• It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells).
• In vitro fertilisation (IVF) is a process of fertilisation in which an egg is combined with sperm in vitro ("in glass").
• of which the expression has regulation effects in reproduction function (oocyte maturation, labor, and sperm motility) and cancer although additional research is required to further define the roles.
• Ferns (Pteridophyta) are vascular plants that have alternating generations, large plants that produce spores and small plants that produce sex cells (eggs and sperm).
• Diaphragm (birth control), a small rubber dome placed in the vagina to wall off the cervix, thus preventing sperm from entering.
• Testosterone release is controlled by the anterior pituitary luteinizing hormone, whereas sperm production is controlled both by the anterior pituitary follicle-stimulating hormone and gonadal testosterone.
• During the procedure, the male vasa deferentia are cut and tied or sealed so as to prevent sperm from entering into the urethra and thereby prevent fertilization of a female through sexual intercourse.
• Twins can be either monozygotic ('identical'), meaning that they develop from one zygote, which splits and forms two embryos, or dizygotic ('non-identical' or 'fraternal'), meaning that each twin develops from a separate egg and each egg is fertilized by its own sperm cell.
• A biological father is the male genetic contributor to the creation of the infant, through sexual intercourse or sperm donation.
• The process begins with fertilization, where an egg released from the ovary of a female is penetrated by a sperm cell from a male.
• In terms of insemination, ICSI needs only one sperm cell per oocyte, while IVF needs 50,000–100,000.
• Genetic sex differences start at conception depending on whether an ovum fuses with a sperm cell carrying an X or a Y chromosome.
• Million progressive motile (million motile sperm cells per milliliter), a measure of male fertility used in semen analysis.
• The bulbourethral glands are responsible for producing a pre-ejaculate fluid called Cowper's fluid (known colloquially as pre-cum), which is secreted during sexual arousal, neutralizing the acidity of the urethra in preparation for the passage of sperm cells.
• Human sex is determined at fertilization when the genetic sex of the zygote is determined by whether the sperm cell contains an X or Y chromosome.
