The process of transforming spermatids into mature sperm cells, which involves significant changes in structure and function.

The nucleus of the sperm cell becomes more compact, making it smaller and more efficient for transport.

The acrosome is a cap-like structure on the sperm cell's head that contains enzymes needed to break down the egg's outer layer for fertilization.

The process of spermiogenesis involves significant structural changes to the sperm cell, including the formation of a flagellum (tail) for motility.

The tail of the sperm cell develops to provide motility, allowing it to swim towards the egg.

During spermiogenesis, a unique structure called the acrosome develops on the head of the sperm cell.

The condensation of the nucleus in the sperm cell is a critical step for efficient transport, allowing the sperm to travel efficiently.

Spermatids are immature cells that undergo a complex transformation called spermiogenesis to develop into functional spermatozoa.

The head of a sperm contains the nucleus, which houses the genetic material (DNA), and the acrosome, a cap-like structure containing enzymes that help break down the egg's outer layer during fertilization.

The midpiece of a sperm is packed with mitochondria, which provide energy for the sperm's tail to move.

The tail of a sperm, also called the flagellum, is responsible for propelling the sperm towards the egg.

The process of gametogenesis involves the production of gametes (sperm and egg cells) through a series of cell divisions and differentiation.

Tunica vaginalis is a double-layered membrane that surrounds the testis, providing protection and lubrication.

Tunica albuginea is a tough, fibrous capsule that encloses the testis, providing structural support.

Disruptions in the process of gametogenesis can lead to infertility, making it a target for contraceptive strategies.

These cells in the testes support and nourish developing sperm cells.

These cells in the testes produce testosterone, which plays a key role in male development and reproductive function.

The outer layer of cells surrounding the oocyte (egg cell) in the ovary.

A thick, glycoprotein layer that surrounds the oocyte and plays a role in fertilization.

Specialized cells in the testes that produce sperm.

The process by which egg cells are produced.

The hormone that is responsible for stimulating spermatogenesis and the development of secondary male sexual characteristics.

The release of cortical granules from the egg cell, altering the zona pellucida to prevent the entry of additional sperm.

The entry of multiple sperm cells into the egg, which can be harmful to the developing embryo.

The fusion of the male and female gametes (sperm and egg) to form a zygote.

The process of development of the follicle (a structure that contains the egg) from a primordial follicle to a mature Graafian follicle ready for ovulation.

The fluid-filled cavity that forms within a developing follicle.

A process that occurs after approximately 10 days, where the corpus luteum degenerates and forms a fibrous structure called the corpus albicans.

A special gland formed by the granulosa and theca cells after ovulation. It secretes progesterone and estrogen.

The first cell of a new organism, containing a complete set of chromosomes from both parents.

A set of chromosomes containing two copies of each chromosome, one from each parent.

The process of aligning chromosomes during cell division, ensuring that each daughter cell receives a complete set of chromosomes.

The nucleus of the egg cell that forms after meiosis I. It contains half the chromosomes of the original egg cell.

The nucleus of the sperm cell that forms after the sperm fertilizes the egg. It contains half the chromosomes of the original sperm cell.

The process where the male and female pronuclei fuse together to form a single nucleus with a full set of chromosomes.

The stage in fertilization where the pronuclei membranes dissolve, allowing chromosomes to align for cell division.

The process where the egg cell is released from the ovary. It's the final stage of oogenesis.

The structure that forms immediately after ovulation, filled with blood.

The stage in the development of the egg cell where the nucleus is transformed into the female pronucleus.

The ovarian follicle that is selected to ovulate. It grows larger and becomes dominant.
