Front 4

Dyspareunia

Back 4

(P. 23)

Pelvic weakness or painful intercourse may result if the tissue does not heal properly.

(P. 24)

The external opening of the cervical canal into the vagina.

Front 7

Follicle-stimulating

hormone (FSH)

Back 7

(P. 27)

FSH stimulates maturation of a follicle in the ovary that contains a single ovum.

Front 8

(P. 24)

The internal opening of the cervical canal near the uterine corpus

Front 9

Luteinizing Hormone (LH)

Back 9

(P. 22)

Secreted by the anterior pituitary gland, in response to the hypothalamus.

LH initiates the production of testosterone in he Leydig cells of the testes.

Front 10

Menarche

Back 10

(P. 27)

Front 11

Menopause

Back 11

(P. 29)

Refers to the final menstrual period, although in casual use the terms menopause and climacteric are often used interchangeably.

Front 12

Obstetric conjugate

Back 12

(P. 26)

The smallest inlet diameter of the pelvic inlet.

Estimated by subtracting 1.5 to 2 cm from the diagonal conjugate (the approximate thickness of the pelvic bone). This measurement determines if the fetus can pass through the birth canal.

Front 13

Oxytocin

Back 13

(P. 29)

Secretes by the posterior pituitary gland. It stimulates contraction of the uterus and dilation of the cervical canal.

Front 14

Ovulation

Back 14

(P. 27)

Occurs when a mature ovum is released from the follicle about 14 days before the onset of the next menstrual period.

Front 15

Ovum

Back 15

(P. 25)

The female reproductive cell; egg

Front 16

Prostate Gland

Back 16

(P. 22)

Front 21

Spermatogenesis

Back 21

(P. 21)

Normal sperm production

Front 22

Transverse Diameter

Back 22

(P. 26)

The largest diameter of the pelvic inlet. It determines the inlet's shape

Front 23

Zygote

Back 23

(P. 25)

A fertilized ovum.
