Regulation of Reproductive Hormones and Cycles

Gonadotropin Releasing Hormone (GnRH)

Neurohormone from hypothalamus regulating LH and FSH.

Luteinizing Hormone (LH)

Anterior pituitary hormone promoting ovulation and testosterone.

Follicle Stimulating Hormone (FSH)

Anterior pituitary hormone stimulating follicle and sperm development.

Testosterone

Steroid hormone promoting male secondary sex characteristics.

Estradiol

Ovarian steroid hormone promoting endometrial growth.

Progesterone

Hormone regulating endometrium and inhibiting LH and FSH.

Corpus Luteum

Structure producing hormones post-ovulation, decays if unfertilized.

Ovarian Cycle

Monthly cycle involving follicle development and ovulation.

Uterine Cycle

Menstrual cycle preparing uterus for potential implantation.

Follicular Phase

First phase of ovarian cycle, follicle matures.

Luteal Phase

Second phase of ovarian cycle, corpus luteum forms.

Spermatogenesis

Process of sperm production in the testis.

Secondary Sex Characteristics

Physical traits distinguishing male and female bodies.

Anterior Pituitary

Gland producing hormones like LH and FSH.

Leydig Cells

Testicular cells producing testosterone in response to LH.

Sertoli Cells

Testicular cells supporting spermatogenesis in response to FSH.

Endometrium

Uterine lining that thickens during menstrual cycle.

Neurohormones

Hormones released from neurons influencing endocrine functions.

Oocyte

Immature egg cell in female reproductive system.

Ovulation

Release of secondary oocyte from the ovary.

Inhibin

Hormone regulating FSH production in males and females.

Seminal Vesicles

Glands producing fluid for sperm transport.

Prostate Gland

Gland contributing to seminal fluid composition.

Bulbourethral Gland

Gland secreting pre-ejaculatory fluid for lubrication.

Follicle Development

Process of ovarian follicle maturation before ovulation.

Hormonal Regulation

Interaction of hormones controlling reproductive cycles.

Fertilization

Union of sperm and egg, initiating pregnancy.
