Micronised transdermal progesterone and endometrial response.
Lancet (London, England)
|October 30, 1999
Summary
Sequential transdermal progesterone did not adequately raise blood levels or stimulate endometrial changes when given with continuous transdermal oestrogen. This hormonal therapy approach was insufficient for achieving desired endometrial secretory response.
Area of Science:
- Endocrinology
- Reproductive Biology
- Gynecology
Background:
- Continuous transdermal oestrogen is used for hormone replacement therapy.
- Progesterone is crucial for preparing the endometrium for implantation.
- Optimizing transdermal progesterone delivery alongside oestrogen requires further investigation.
Purpose of the Study:
- To evaluate the efficacy of sequential transdermal progesterone in achieving adequate endometrial transformation.
- To assess the impact of this regimen on circulating progesterone levels.
Main Methods:
- Administration of sequential transdermal progesterone with continuous transdermal oestrogen.
- Monitoring of circulating blood progesterone concentrations.
- Assessment of endometrial response (histological examination for secretory changes).
Main Results:
- Transdermal progesterone failed to significantly increase circulating progesterone concentrations.
- The regimen was insufficient to induce a secretory response in the proliferating endometrium.
Conclusions:
- Sequential transdermal progesterone, when combined with continuous transdermal oestrogen, is not an effective method for achieving endometrial secretory changes.
- Alternative or optimized delivery methods for transdermal progesterone may be necessary.

Fertilization
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...
Transcytosis of IgG
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Gonadal and Placental Hormones
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...

Ovarian Cycle
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
Intrauterine Drug Delivery Systems
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...
