The infundibulum, with its fimbriae, sweeps oocytes into the oviduct's opening (ostium).

The ampulla is the location where fertilization usually occurs.

The isthmus forms one-third of the oviduct's length.

The uterine tube has three layers: serosa (outer), smooth muscle layers (middle), and highly folded mucosa lined with ciliated epithelium (inner).

The uterus has four regions: fundus, body, isthmus, and cervix.

Paired erectile tissues located dorsolaterally to the corpora spongiosum.

The single erectile tissue that surrounds the urethra, crucial for maintaining the urethra's function during erection.

Maintains optimal temperature (34°C) for sperm production.

Structures in the ovary containing developing germ cells (eggs).

Steroidogenic cells that convert cholesterol to androgens.

Cells that maintain and mature oocytes, converting androgens to estrogen.

Endocrine organ formed from granulosa and thecal cells and secretes hormones; critical for maintaining pregnancy.

Structure that replaces the corpus luteum if pregnancy doesn't occur and is resorbed.

Structures that carry eggs from the ovary to the uterus.

Blood vessels supplying and draining the ovary.

Area where blood vessels and nerves enter or exit the ovary.

Protective layer surrounding the oocyte.

Mature follicle containing fluids and mature egg.

The route of sperm and seminal fluid during ejaculation.

The process of sperm production.

The stage of puberty where the adrenal cortex increases androgen production, typically starting around age 6-8.

The stage of puberty where gonads mature, enabling them to produce gametes and steroids.

During male gonadarche, the primary hormone produced is testosterone.

During female gonadarche, the primary hormones produced are estrogen and progesterone, along with growth hormone, insulin, and thyroid hormones.

The climacteric is the transitional period in both males and females where reproductive years end.

Receives, retains, and nourishes the developing fetus during gestation.

The uterus has three main layers: perimetrium (outer serosa), myometrium (muscle layers), and endometrium (lining).

The endometrium has two layers: the basal layer (permanent, with glands) and the functional layer (hormone-responsive) which grows and is shed during periods.

The vagina is the copulatory organ, birth canal, and passageway for menstrual flow.

The vagina consists of three layers: outer adventitia, middle muscularis, and inner mucosa.

Includes structures like the mons pubis, labia majora, labia minora, and the clitoris.

The area between the labia minora, containing the vaginal opening and ducts of glands.

It is an erectile body homologous to the penis, rich in nerve endings, and important in sexual pleasure.

Hormonal control system regulating gametogenesis and steroid production in both sexes.

Hormone released by the hypothalamus, stimulating the release of LH and FSH.

Phase of the ovarian cycle, where a follicle matures in preparation for ovulation.

The phase after ovulation where the corpus luteum forms and produces progesterone in preparation for pregnancy.

Recurring cycle of changes in the ovaries and uterus to prepare for potential pregnancy.

Biological process of becoming sexually mature.

Gonads in an embryo have the potential to develop into either ovaries or testes depending on genetic factors.

The process of producing gametes (sperm and egg cells).

The production of eggs (ova) in females.

The earliest precursor cells that will develop into sperm or egg cells.

Sertoli cells are responsible for supporting and nourishing developing sperm cells in the seminiferous tubules. They also contribute to the seminiferous fluid.

Tubules within the testes where sperm cells are produced.

A coiled tube that connects the seminiferous tubules to the vas deferens. It stores and matures sperm.

A tube that carries sperm from the epididymis to the ejaculatory duct.

Glands that produce a fluid rich in fructose and other substances to provide energy and nourishment to sperm.

A gland that produces a fluid that helps to activate sperm and protects it from the acidic environment of the vagina.

Glands that produce a clear, alkaline fluid that lubricates the urethra and neutralizes any remaining acidic urine.

The male external genitalia, composed of erectile tissue, urethra, and glans penis.

The scrotum is a pouch that hangs outside the body to regulate the temperature of the testes for optimal sperm production.

The cessation of menstruation in women, marking the end of reproductive years.
